v2.2: Web Ui V2, bug fixes, cache improvements

This release is a little rushed but I wanted to get some bug fixes out there. The biggest changes are to the Web Ui v2 and initial startup script. The display seems to be working fine but there are some things in the web ui that don't work.

DO NOT USE THE EDITOR BUTTON IN THE WEB UI it' s very broken and you'll have to restart your pi.

BREAKING CHANGES:
After pulling the latest release, you need to execute sudo python start_web_conditionally.py to install the dependencies for the Web UI v2. It will likely error out when running this.

When it is done, run chmod +x first_time_install.sh followed by sudo bash first_time_install.sh, which resets permissions, sets automatic starting of the webui v2, and -tries- to clean everything up.

When you reboot you should get the web ui automatically started as long as "web_display_autostart": true in your config file.
