Some cleanup to Daddio skin.

Basic resourceloader support, fix Modern include

Also rename class file to meet the precedent set by
other third-party skins of having the templates at
Skinname.skin.php.

Some cleanup of Daddio skin.

Various improvements, or at least I hope this is an improvement over the
status quo.

Untested, but mostly based on MonoBook, so it should work(TM).
