[needs-packaging] Unity 100-scopes

Unity trunk (lp:unity) recently merged in the project (functionality) of 100-scopes [1]. This forces a requirement for new packages, each related to a separate, new scope for Unity. Without those packages in the universe the new functionality cannot work properly (see bug LP: #1154229 for more details).

Normally, we should submit one bug per package, but with this number of packages needing releasing, it would be really troublesome to maintain. That's why, as advised by Mathieu, I created one big bug for all of them and attached the scope projects as 'affects'. This way we can somehow maintain which packages have been released and which not.

All of the new packages already have proper packaging in their branches. All of them are already included in the daily-release process, so the latest versions for every scope is available in the 'staging' daily-build-next PPA [2] (targetting the next PPA [3]). If packages need testing, please use the packages from one of the two mentioned PPA's.

List of new packages:
lp:unity-scope-audacious
lp:unity-scope-chromiumbookmarks
lp:unity-scope-calculator
lp:unity-scope-clementine
lp:unity-scope-colourlovers
lp:unity-scope-devhelp
lp:unity-scope-deviantart
lp:unity-scope-evolution
lp:unity-scope-firefoxbookmarks
lp:unity-scope-gallica
lp:unity-scope-gdrive
lp:unity-scope-github
lp:unity-scope-gmusicbrowser
lp:unity-scope-googlenews
lp:unity-scope-gourmet
lp:unity-scope-guayadeque
lp:unity-scope-home
lp:unity-scope-launchpad
lp:unity-scope-manpages
lp:unity-scope-musique
lp:unity-scope-openclipart
lp:unity-scope-openweathermap
lp:unity-scope-soundcloud
lp:unity-scope-sshsearch
lp:unity-scope-texdoc
lp:unity-scope-tomboy
lp:unity-scope-virtualbox
lp:unity-scope-yahoostock
lp:unity-scope-yelp
lp:unity-scope-zotero

All of them also require inclusion to main, but we will handle that with a separate MIR bug once this one is resolved properly.
