Merge lp:~didrocks/unity/desktop_label_fixes into lp:unity

[Didier Roche-Tolomelli]

Fixes:
- Focus the desktop when the desktop is mapped and that there is no other window around (focus on startup in particular) (LP: #863037)

- Show the 'Desktop' label when desktop has been focused (LP: #863129)

[Jason Smith (jassmith)]

we dont do m prefixing anymore please_use_this_style_ :) (note the trailing backslash)
