Updated to Eto 3.x (the current version).
Removed Xwt libraries.

Added a basic form, in which the textbox does
	not update correctly yet.
Thirdparty library cleanup.
Moved shp -> png logic to libshp.

Selecting files and converting via GUI is possible!

Added MacApp project for eventual .app bundle.

Annoying hack that forces the OpenFileDialog
	to begin navigation from Documents directory.
