Release urgent bugfix v2.6.5 (Stable Tag 2.6.5).

Also add a temporary tag for another bugfix.

- Bugfix: Editor buttons: debug button by reverting name change in PHP file while JS file and HTML template remained unsynced, thanks to @gova bug report.
- Bugfix: Hooks: default-disable the_excerpt hook with respect to theme-specific excerpt handling, thanks to @mmallett bug reports.
= 2.5.13.1 =
