[FIX]Naming Consistency: 'Featured Site Profiles'

git-svn-id: file:///var/local/code.tiki.org/tikisvn/branches/12.x@49526 b456876b-0849-0410-b77d-98878d47e9d5
[NEW]New screens at the Site Profiles Wizard, as suggested earlier in the devel list and in http://dev.tiki.org/Profiles+Wizard : one for potentially useful profiles for production sites (Mobile, etc), and another to showcase some features for demostration purposes. 
[MOD]Names for the former profile-related wizard files and functions have been renamed to allow other cases to be added (Useful and Demo), and apply-profile links open in new window, so that user can continue revising other profiles from the wizard before finishing it.
[NEW]Icons have been added to all profiles in the Profile Wizard, to make it a little bit more user friendly (too much text still maybe?). all of them taken from openclipart (public domain icons): https://openclipart.org . They could be modified to have a similar color palette, since we have the svg version for all of them except the togetherJS one.
