Make gdlint compliant

- Shorten descriptions
- Reorder 'extends'
- Remove whitespace
- Remove unused function
- Remove unnecessary else: return
- Fix 'start_xr.gd' static variable declared out of order
     - Unsure if this fix should be in this PR, but it clears the last of the gdlint errors even though this file was not previously changed in this PR.
