2.13.4 with usability improvements

MirrorBrain 2.13.4 improves usability of the mirror scanner, by adding a terse report format (which makes it easy to spot problems), and a totally quiet mode where only errors will be output. Surely something that everybody has been waiting for (and myself not the least).

This release also improves usability in some other corners, and adds important documentation. Noteworthy are the added instructions on setting up automatic GeoIP database updates. See the 2.13.4 release notes for details.

Packaged binaries are built and ready for upgrading. You will find them on the download page, as usual.

Thanks everyone for their support!
