manifest: add __nonzero__ method
This adds a __nonzero__ method to manifestdict. This isn't strictly necessary in
the vanilla Mercurial implementation, since Python will handle nonzero checks by
using __len__, but having it implemented here makes it easier for alternative
implementations to implement __nonzero__ and have them be plug-n-play with the
normal implementation.
