Several changes to get development builds working

I fixed a require path precedence issue that was causing development
runs to load installed Rainback paths, rather than using the source tree.

I also renamed the "development" boolean to "installed", as this is a
more conventional naming (at least, it's inline with my other projects
that use this method)
Added activateWindow support to QWidget bindings
Support QWindow creation from Lua
Further fixes to the make run* paths
