Update v1.15.10

Red Box v1.15.9 — Tile Set Search

You can now:

• Search tile names directly inside each selector.
• See the first five matching options.
• Press Backspace to edit the search.
• Press Esc to close the selector.
• Click outside to close it.
• Select tiles for full inner, full outter, edge, inner corner, and outter corner.

This makes configuring large tile libraries much faster.
