Don't require restart to change release number

[zzz]

str4d says the website should recognize when the release number changes in init.py. Usually but not always, however, a restart is required. zab says that since the .py must be compiled to a .pyc, a restart is always required. Figure out who's right, and why, and fix it so a restart is never required.

If I'm right about the .pyc compilation, then this approach may help ​https://www.indelible.org/ink/python-reloading/ but it's not trivial at all.
