The send_email function wasn't successfully parsing ; or , separated email address lists. I simplified it's processing.
While I was at it I removed the "valid email" check from email_test.php because that step is already being done in the send_email function that is called and it safely returns the appropriate error. I would have had to rewrite that function to handle the multiple email lists otherwise.
added information on image resolution for wallpaper as well as a few descriptions that are useful when learning the options available to be configured in the template.
Grandstream: Hide BLF Remote Status And More Distinctive Ring
Hide the other connected party on the BLF of supported phones. When not hidden a busy BLF will show the other connected party/sttaus of the call by flashing back and forth between the BLF label and the caller ID.
It also impacts the park buttons, but they typically only show the word "park" because of the character limitations.
Also did more effective find/replace for the distnctive ring variables with regex! (plus a typo was made in the previous version)

Support enabling nway conference with Grandstream phones if nway_conference is set to true. If it is not true, it sets the conference URI back to blank to restore local conference
Grandstream template updates to support plantronics EHS via grandstream_headset_type and grandstream_headset_key_mode variables.
Also updated wallpaper and screensaver if/else statements to leave out the variables if they are not defined instead of clobbering the user setting. If you want to mandate a certain setting, just set the variable. If the variable is unset it will not overwrite on provision and allow the previous setting to remain.
