[Moin-user] new moin2 theme

[Thomas Waldmann]

the good news: I am currently working on a new moin2 theme.

I did a clean start from zero, NOT copying complete old css.

Currently, the "show" view already looks quite nice (lots of other stuff
is still very broken):

as you see there, there is still quite some css missing (e.g. those
paragraph symbols in the headlines should be hidden usually).

I will try to get that stuff to a "not totally broken" state ASAP
(before pushing it to main repo), so we maybe can even have some Google
Code-In theme tasks.

btw, I need a name for that theme, currently it is named "foobar".

the bad news:
* it might be that while cleaning up the whole html/css/layout mess, I
have to break compatibility to the moin2 modernized theme as it is now.
* flask-themes extension is broken for loading templates from the theme
for flask >= 0.8 (which we use), I did a quick fix, but have no idea
whether it is complete, see the flask-themes issue tracker. as long as
we can't easily get a fixed version/release for that, this is a blocker
(or at least a major annoyance).
