Setup: Remove RELEASE-VERSION after builds.

When running from a git checkout, show the git version instead.
Change error reporting from exceptional.io to a SquareSquash instance at bugs.mcedit.net.

Exceptional.io is nice, but it is not appropriate for versioned desktop apps because it is designed for web apps where the latest version is the only deployed version.
Fixed: parentDir was an empty string when running from source.

Use abspath to avoid getting an empty string for the folder containing the script, when not frozen.
