Add prebuild script
Add draft of prebuilding. Unfortunately there's some bug with the repo names

Conflicts:
	js/controllers.js
Do not use current import URL, but the one for the repo which was imported

Fixes the bug where the wrong name for the repo was displayed

Conflicts:
	js/controllers.js
Added files to .gitignore
Precaching and prepopulating changes

Made the precaching script run separately from run.sh
Prepopulating list is added to js/controllers.js in the Dockerfile
Load repositories in a deterministic order
