Add database backend (SQLite) (#26)

Add database with background information for each pkgbase, for possible future use.
A static status page is generated from the db.

Currently includes:

* sub-packages
* build-time
* build-duration
* status (failed, latest, skipped, queued, building, build)
* version (both from PKGBUILD and repo)
* last checked

Database is currently only used for informational purposes. Goal is to refactor many (expensive) methods to use the db instead of searching/parsing files.
