Use forge from db (#1417)

This is the first step towards support for multiple forges (#138). It
inserts a forge using the currently existing env varaibles into db and
uses this forge from db later on in all places of the code.

closes #621

addresses #138 

# TODO
- [x] add forges table
- [x] add id of forge to repo
- [x] use forge of repo
- [x] add forge from env vars to db if not exists
- [x] migrate repo.ForgeID to the newly generated forge
- [x] support cache with forge from repo
- [x] maybe add forge loading cache? (use LRU cache for forges, I expect
users to have less than 10 forges normally)
