missing docs, move some stuff from etherpad to src

Issue #16 resolved

== etherpad == there are quite some "working docs" on the etherpad.

http://etherpad.osuosl.org/whoosh-moin

some of the ideas from there should be MOVED to the source code, to explain why stuff is implemented exactly like that and not otherwise. other stuff might be just discarded.

in the end, we should be able to discard the etherpad, because it is empty and not needed any more.

== docs in general ==

there should be more high-quality docs. :)
