Update qtoolalign (Fixes issue 704)

- Removes shortcut ctrl-a for align tool
-- to avoid ctrl-a for select all text in UI controls messing up prim selection
- Adds llselectmgr select all function
-- to replace ctrl-a select all prims functionality that was a side effect of qtoolalign having this shortcut
- Adds toggle button (up/down arrow) to build floater for toggling display of the lower tab container area
-- This is to satisfy users who relied on ctrl-a to use align while the build floater was minimized and out of the way
- Syncs qtoolalign from Alchemy
