Added check to fetch remote updates before actually pulling in remote
changes.
This may help somewhat with the modification of files when they are
simultaneously open in vim, though I am not entirely sure.
Needs further investigation.
Added service to automatically commit changes in notes directory (every
2 minutes) and automatically push them to their remote origin (after no
changes occured for an hour).
Uses git and systemd to work as a service in the background. Gets
restarted on failure.
