Request adhocracy_ko resource outside of tile (fixes #427)

Tile caching can leed to fanstatic resources not being requested if a
template isn't rendered but taken from the cache.

This happens in the show proposal page, which includes selection tiles,
which need adhocracy_ko, which is missing if the tiles are taken from
the cache.

This commit therefore makes sure the fanstatic resource isn't requested
from within the tile.
Fix changing norms from within proposals (fixes #406)

The behavior of PickleType has been changed in SQLAlchemy 0.7 such that
changes of such attributes aren't detected automatically anymore. This
commit restores the previous behavior.

This needs to be touched again when moving to SQLAlchemy 0.8, as the
mutable flag will then be removed and we have to create a custom data
type for the variants list, which inherits from the `Mutable` mixin.
Added the `RequestLog` Model to the possible exports

Added `gzip`, `tgz (tar.gz)` and `tbz (tar.bz2)` to compression methods for exporting
Added mime-types for the contents to the response.

Changed rendering in an abstraction method `_render_json`,
to implement further render methods for `protobuf` or other similar structured datatypes.

Make post register/login urls configurable (fixes #431)

This allows to define post register/login urls and instances, which a
user is redirected to after succesful register/login, if no came_from
parameter is set.

If these options aren't set, the user is redirected to the dashboard
instead.
Merge branch 'develop' into export-requestlog
Removed the "csv" option from the formencode, the code responsible to handle this option is thrown out, due to nested dict structure of the export data, that the "csv" format not easily could represent.
