* More Yealink fixes
-Spelling
-Wrong var
-Updated power_saving schema to be uniform across all devices to best written variable logic. - Good job whoever built it. IF YOU HAVE SET THIS UP IN THE PAST IN THE OLD FORMAT IT MAY BREAK. $yealink_powersave_* vars have been depreciated in favor of $yealink_ps_* since logic has been built to allow more with less total vars.
-Added some documentation
nway_conference == true was evaluating as true regardless if nway_conference was set to true or false, just as long as it had a value of any kind.
This also fixes it so that you can set nway_conference to false in the default settings and it will disable the network conference feature, previously once it was enabled on yealink phones it could not be disabled without manually changing it in the phone or a factory default.
* Updates to Yealink codec provisioning
Changed codecs to use variables set in default settings.
* Added basic provisioning for swissvoice cp2502 and cp2505g
Codec handling set in default settings.
Need to still work on directory and funtion keys.
* Update app_config.php
