Ticket #4548.

Same behaviour as speeddial function key.

4.0.4 and 5.0.0 use the same 000000000000.cfg and common.cfg files, so
keep only one copy in the common directory. The previous common.cfg file
in the common directory was no more used since the removal of the 3.X
plugins..

Also, update the style to the same style used in base.tpl, i.e. flat.

Also, use the default "autoanswer" ring tone class.

They were only used by the xivo-polycom-3.1.6 and xivo-polycom-3.2.4B
plugin, which have been removed.

fix section name for firmware, fix missing value for blf, and added blf and speedial for 71 firmware (memory is now line)
