Please backport cinnamon 2.2 and related software from vivid to trusty

[Fantu]

During the development of trusty cinnamon debian packages was old and with many problems, after they had 3 new maintainers and now 2.2 packages are present in debian 8 and vivid and are good.
I think can be good add them in trusty-backports.

I already tested it in trusty and the needed changes are:
cinnamon: needed changes already in 2.2.16-5ubuntu1
cinnamon-desktop-environment: needed changes already in 2.2.4ubuntu1
nemo and cinnamon-menus: in gir .install file usr/lib/*/girepository-1.0/...->usr/lib/girepository-1.0/

For now part of cinnamon packages are not present in trusty and other are old, users that use packages present (for example nemo) have many bugs already solved in 2.2.
Many other users install/upgrade it from other repositories having problems like these:
https://bugs.launchpad.net/ubuntu/+source/cinnamon/+bug/1279762
https://bugs.launchpad.net/ubuntu/+source/nemo/+bug/1374673

If you need more informations/tests tell me and I'll post them.
If backports will be accepted but builds ready and tested are needed I'll prepare all updated packages in launchpad ready for upload.

Thanks for any reply and sorry for my bad english.
