For #8 : Tileset editor window mostly working

* Tileset editor window appears with notes, buttons, tilesetproperties, etc.
* Introduces a skeleton and placeholder for TilesetDisplay.
* The text controls on the right aren't autosizing correctly, and they're too small

Midstream on #8 - sizing problems.

midstrean on #8 - sizers mostly fixed, still some min sizes to set

Resizing works as expected now and minimum sizes enforced, moved the buttons for #8

For #8 midstream, all resizing works as expected now
