Cleanup and setup of drop down widget

Got an initial variant of the drop down widget, not completely set on it..
I put some more time to figuring out how I'm going to be ideomatically constructing the widgets. screen.odin I think its getting pretty close to what it will be like.
I'm ready to start lifting the input box. I'll be adding the constraints when I lift it.

Added the option to toggle the debug text in screenspace
Added the fixes from the ui_layout_children_horizontally for margins to ui_layout_children_vertically

Known issue:
There is a bug with test_whitespace that forced me todo a null check on a box. Not sure why.
It needs to be redone anyway.. (compose it with the h/vboxes instead)

There is some sublime files added in, started to use it.
