init: don't abort Mercurial on version mismatch

Evolve causes Mercurial to exit if there is a version mismatch, even
if no evolve command is invoked. This is a headache for people who
have to work with multiple versions of Mercurial. Instead, raise an
ImportError, which gives a warning but otherwise allows Mercurial to
run non-evolve commands.
