Suggestion: Add functionality to change text views default font

**Currently**
Each text view is defaulted to KorGE's default font. To change the font the `font` variable needs to be set for each new text view created.

**Suggestion**
Add a way to allow setting text views default font once so that each text view created afterwards defaults to that new font.

Start by locating KorGE's text-view implementation and the existing font assignment path; the issue does not name a file or test. Trace how newly created text views receive the default font, then define and verify a way to change that default so later text views use it without per-view assignment.
