In effect, this is a combination of two of the previous pickers:
the location picker, and the editable string picker.
This required quite a significant rework of how the tilemap places its children.
Currently it's only used in special node editing.
I plan to add its use in many other places too though.
These were very shoddily put together!
It seems the person who made them never really tried building
the editors or the tests.
Also included here are a couple of minor source changes that are needed
to make the project files build.
* Fix non-relative include paths for resources
* Fix one file path for the tests build
(Currently tests crash for me, but at least they do compile?)
* Remove old VS project junkfiles from gitignore
* Fix missing resource compiler include paths for Release builds
