Rewrite in more structured Bash (#1)

* Add .gitignore

* Update readme.md

* Begin rewrite

* Fix enablement control ops

* Change permissions on logfile
allows rwfus --status to log even when run as deck user

* I've taken entire classes about linux security
*Why* did I think $EUID would work for that? Jeez Louise.

* Systemd, please stop my units

* Remove description in overlay mounts

* Actually create work dirs (oops!)

* Disable systemd log in stat_units
if you want specific details, use `systemctl status <unit>`

* Colors and newlines

* Check for permissions
The actions will fail anyway without perms, but it's good to check

* Exit if arg parse failed

* Fix exit on invalid opt

* Allow executing as nonroot in TESTMODE

* Summarize systemctl status output with the power of grep

* Lazy-unmount the mountpoints
This allows /usr/ to actually be unmounted

* Stat units after enable/disable to prove status change

* Remove memes for release, mark helptext

* Turn off stat by default
unless an enablement control operation occurs

* Stat after install, for the fun of it
Don't log the stat, because it'll put a ton of terminal escapes in the logfile

* Move testmode text to version string line.
