The following updated on this commit:
1. styleboxflat .tres for white and black removed border. As mentioned in the chat, we probably want a different one of these for each (with and without borders)
2. set the baseline font for the TextEdit
3. selected increased font size for the label default
Adds asset folder with the two themes, the fonts and styleboxflats for each.
We discussed keeping this themes location updated and adding it to all projects when we begin work.
