Shellcheck:
- Fixed all warnings
- Not tested extensively
Logfiles:
- Logfile location changed
    - `/var/log/rwfus.log` now
- Logfile not wiped on init
    This allows logfile to be continuous
    TODO: improve logfile to include timestamps

- ignore rwfus.conf

It's a surprise tool that will help us later

- Actually loads config files now.
    - How did I miss that?
- Actually stores config files now.
    - Loaded config options are marked CF_REQUIRE
    - CF_REQUIREd config options are uncommented
    - This is kinda jank, but it's bash. Jank happens.
- Config file specifies which systemd units to enable, disable, and mask now
    - This fixes #12
- Rwfusd now aborts and unmounts if it can't successfully mount_all
    - This should hopefully make it less painful to work with in the event of a catastrophic failure.
- Preparations have begun for porting parts of the script to a better language
    - I hope I can actually do that sometime. Bash is syntactic-sugar-coated hell.

Mute them.
