Milestone 10

Last week, I developed a new basic layout for the module, which is much more modular and flexible, and e.g. allows for multiple searches on one server/index.
To this end, I have moved development to HEAD (to keep the DRUPAL-6--1 branch in a working state) and already modified most of the module, only the admin settings are now left.

Ongoing:

• #530452: Improve UI
• #530456: Add Advanced Search form(s)
• #530466: Add facet blocks (and options)
