Small Fixes

Small update of bug fixes I encountered running  a session

-Units with size traits and with auto size enabled will not adjust if the size is edited in the piece after spawning it.

-Fixed size trait of the Brute basic job.

-Creating a second unit right after creating one will not lock the creating screen.

I'm still running the campaign and building stages, so it's very probable a new small fix will come not long enough. See you then!
