Add Ability to Set Line Key Label Length via Provisioning Template

[kismetgerald]

While setting up my provisioning template for the T46G, I noticed in the web interface of the phone - top of the DSSKey menu - there is a setting to change the "Label Length" to Extended. This is very desirable, unfortunately, there isn't a tool-tip that provides the setting that can be used in the provisioning template.

I would therefore like to request that you support the setting of this feature in the provisioning template. Something like this will do:

"phone_setting.dsskey_label.length" = Exended or Default

Thank you.
