Fix the commit reference mapping `<leader>grc` in the case that nothing
follows the commit hash on the line. In that case the join would add a
trailing space.
`gJ` is not suitable as that would break in the other case that text
follows. When splitting the line behind the commit hash, the space in
front of whatever follows is deleted. Thus when joining everything
together at the end, there would be no space between the closing
parentheses and the rest.
Using the `system()` was the only solution I found to insert the subject
directly behind the hash without destroying the formatting and the text
behind it.
For this to work the trailing newline had to be cut off of git's output.
[vim-tmux-navigator][1]:
> Seamless navigation between tmux panes and vim splits
Add the hybrid vim/tmux plugin `vim-tmux-navigator` to switch between
tmux panes and vim splits with `C-[hjkl]`.
Add vim-tmux-navigator as a submodule in tmux/plugins and create a
symlink from vim/pack/plugins/start.
Get rid of similar switching keymappings in the vim and tmux configs.

- Drop the mapping for `:Gcd` as I rarely use it and prefer to commit
with one keystroke less.
- Add the current file instead of calling `git add -p` for the whole
repository. If I want to add hunks I can do that with the gitgutter
mappings.
- Add mappings to stash and checkout the current file.
- Use mnemonic 'add' instead of 'stage' for `GitGutterStageHunk`
mappings.
