Preparing for a release.

Picked up after quite a busy period.

- Making it run out-of-the-box with DB=user
- Making it run testcases out-of-the-sourcetree.
- Fixing cmake deficiencies.
- Bumping up version to 0.8_rc1, hoping to run 0.8 soon...
  0.7 was de facto 0.7_rc2.

Roadmap:
- Test, test, test.
- Get it into Debian unstable.
- Publish 0.8. It it works nice, bump it to 1.0.
- Ignoring mysql/ldap DB settings until public declares it's useful.
