Option to gently fade chaperone to disabled below a certain height (#622)

* Option to fade out chaperone when HMD goes below a configured height

Useful for setups in which you have a seat just outside your VR space,
or like to sit in the middle of your space for any amount of time. Will
fade out the boundaries to 0% opacity over 5 seconds, 5 seconds after
you sit down. Standing back up to the configured height will make them
pop back in immediately.

Can be found under Chaperone -> Additional Settings.

* Update format.sh to require clang-format v10

* Use fade distance instead of opacity, opacity inconsistently applied

* Bugfixes (#624)

* stop crashing on HMD Init Errors, as well as bypass force quit on all steamvr Init Errors

* add qtc clang to gitignore

* add app volume adjustment

* adjust app volume placement in menu

* fix type error

* increment version

* fix version number
