make class to manage amp_conf settings (freepbx_settings)

(In [10953]) initial changes for amportal.conf class setup (probably will want to rename config.functions.php to freepbx_settings.class.php) re #4740 - partially done but should still be operational

We probably want to use something like of $freepbxconf? or $freepbx->conf() (vs $freepbx_conf), so that the $freepbx object can be extended to include a lot more than just settings. Also, considering that your passing by reference, you may want to go all out and make the object a setter as well.

you input is pretty vague, you may want to clarify a bit.

As far as the pass by reference, it is simply to bridge the gap for now that almost everything uses $amp_conf which isn't going to change over night, though we will probably want to move at some point to using the class more properly for the settings. Making it reference will allow for any behavior that may be happening 'out there' where someone is setting it that we are not aware of, stay consistent as people do move to puling the information from the class.

(In [10959]) mostly finished with config.functions.php re #4740

(In [10961]) changes to schema and migration info re #4740, this migration method will probably change though bug for now...

(In [10962]) don't use sql() as will probably want to use as part of install_amp, and a few fixes re #4740

(In [10964]) validation on some optional settings when defining re #4740

(In [10965]) partially done work to intialize freepbx_settings, will replace migration insert table, the plan is that we will be able to run this from framework modules or install_amp like ugrades, need to make sure we can run this class from install_amp though re #4740, this work is untested and should not currently do anything

Reassigning so that I remember to take a closer look

(In [10969]) more prep for creating all settings and found a bunch more that were not accounted for re #4740, still have not tested it, will do so tomorrow

(In [10970]) add freepbx_settings to various modules and misc minor tweaks re #4740

(In [10972]) change from config.functions.php to freepbx_conf.class.php re #4740

(In [10975]) convert falses from conf file and provide optional to not commit re #4740

(In [10977]) couple errors re #4740

(In [10979]) get freepbx_conf re #4740

(In [10980]) adds freepbx_settings to newinstall sql schema re #4740

(In [10981]) install_amp needs access to die_freepbx, and enable freepbx_settings_init re #4740

(In [10982]) fix duplicate setting and add AMPWEBADDRESS re #4740

(In [10984]) key should be $key re #4740

(In [10985]) initializ freepbx_conf re #4740

(In [10986]) typo and make sure not only exist but is a proper object as some situations during testing resulted in this subsequently becoming cleared but still existing re #4740

(In [10993]) adds get_conf_settings method re #4740

(In [10994]) more changes to use class methods and other tweaks and notes re #4740

(In [10995]) oops get_conf_settings properly this time re #4740

(In [11003]) make category madatory even for modules, makes things more clear re #4740

(In [11010]) get rid of UINT, adds validation and method to check results of last update re #4740, this checking may momentarily break stuff as it has not been tested with setting values, about to do that so fixes to come shortly

(In [11012]) adds range and emptyok info to tooltip re #4740

(In [11014]) changes ajax to json, sends back result array used in messaging, resets value if changed to something else, added a couple methods to freepbx_conf array re #4740

(In [11026]) add name field and use more friendly names re #4740

(In [11028]) adds freepbx_settings to i18n module utility re #4740, non-modules settings are generated for framework module

(In [11031]) adds reset_all_conf_settings method so we can add a cli ability somewhere to restore a damaged system, re #4740, good call Tony

(In [11035]) make sure INT value is numeric or blank and set to blank if not re #4740

(In [11058]) moves generation of amportal.conf to retrieve_conf and adds method in freepbx_conf to generate re #4740

(In [11061]) this should be 100% documentation and re-organization, no code changes re #4740

(In [11071]) closes #4758 as well as updates mulitple modules to use this (and a tweak to one view) re #4740

affectively complete, new issues or request changes should have new tickets opened against them.

(In [11110]) use existing attributes on define_conf_setting if setting exists and attributes not sepcified re #4740

(In [11111]) missed a few default settings re #4740
