Merge lp:~mterry/unity-greeter/move-names-after-monitor-switch into lp:unity-greeter

[Michael Terry]

This fixes the problem where after switching to a different monitor, the names in the user list would get screwed up, position-wise.

It moves the names after a size allocate. And it also fixes an issue with name allocation, where we weren't taking the existing allocation.x/allocation.y into account. This didn't matter before, but when allocating inside an existing allocation, it does matter. (I'm not entirely sure why GTK does that magic for us when not inside an allocation.)
