Merge lp:~vanvugt/unity/fix-960957 into lp:unity

[Daniel van Vugt]

Don't respond to "Confirm" actions in showLauncherKeyTerminate, which come
from pressing Enter during any action (holding Alt). Those calls are spurious
(a long-standing design bug in compiz) and do not come with a valid options[]
vector. So accessing options[] would crash (LP: #960957)
