Works with magit-next for now.
Tests to update and evilify functions robustness need to be improved.
Does not work 100% with magit-mode-map because it is created with
`make-keymap` and not `make-sparse-keymap` and `map-keymap` does not
seem to work with `make-keymap`.
Load paths are now registered in `core/load-paths.el`
Libraries are in `core/lib`
Move `ht.el` to `lib`
Add `mocker.el` to `lib`
Tests are in test,
- unit tests files suffix is `utest.el`
- functional tests files suffix is `ftest.el`
