Do not pass tuples to MirrorGroup.

[bergmannf]

Pass a list[str] as the mirrors argument.

Update the logic derived from urlgrabber components to split the
received strings into the three-tuple (host, path, query) as needed.

This partially resolves #29 (4 tests remain failing for me).

Given that this changes code interfacing with urlgrabber I
assume I might also just be using an unsupported version of
that dependency, where the interfaces were changed.

Hmm I just had a quick glance at it: the current code breaks the python-urlgrabber 3.9.1 support.
