Title: Disable experimental features iff we're on a stable branch.

Current experimental features are:

- The GUI
- The `upgrade` command.

If we're on an unstable branch (which includes master, and anything branched from it), we should work as normal.

This also gives us the version number on the help screen, and flips a previous custom exception to a kraken.
