this commit adds a default keybinding for the vc-gutter hydra (leader-g
.) if both vc-gutter and hydra are enabled. It ensures that the various
vc-*-log-view-modes open up in emacs state, and it adds hg, svn and bzr
to the list of vc backends handled by git-gutter
Phasing out the +module@name convention for plain old
+module-name-hydra, which is more compatible with elisp reflection tools
like describe-function and such.
Also, Emacs starts up faster now. Tee hee.
