This takes jonasc's change, and applies it to all template writing. Also
removes the dependency on mktemp, and only moves files if they are
successfully written.
This prevents problems with programs which watch the file for changes and will
first be presented an empty file.
One such example which will show a notification message about an empty config
file is Alacritty.
By writing to a tempory file and then moving it (atomically?) to the real
location this problem is mitigated.
Update version number and update documentation

Support is inherently provided by `enter`, which now supports a command.
I've added a `git-crypt` command, which is really just an alias
under-the-hood for "enter git-crypt".
