This branch:
- fix an issue with repeated key (LP: #750535)
- reduce shortcuts label size and change some super behaviour (LP: #747812)
- additional cleanage (signals and code)
- prevents false positive "bring the dash" positive even when we are in scale
mode (not directly handled by unity) (LP: #751102)
- Avoid spamming the launcher with state change when the state is finally the
same. (Launcher and Hover machine). That will hopefully fix the "click
through" bug when the Launcher wrongly stay visible (half of bug LP: #744325)
- move the position of the icon on timeout drag. Fix a potential crasher as well
(LP: #751196)
