magit-log-all has the same with the old magit-log: show the commit log
immediately without asking for revision. We should use magit-git-log for
smoother transition to magit 2.1.
Calling `magit-blame-mode` directly is not advised as of Magit 2.1.0,
and will leave a buffer in read-only mode upon exit. `magit-blame` also
allows recursive blame upon repeated usage.
Set git-use-magit-next to t in the layer variable to use it.
For now magit-ghpull from github layer is disabled.
A LOT of issues with next magit and evil remain to be fixed
