First shot at creating+viewing groups
removed tab != space problem
temporary removed hbtm: persona->group
Implemented showing all groups, added groups do debug view, minor bugfixes on creating groups
Added create-star form to group page. Creating not yet working
fixed creating stars in groups
Universe page und persona page don't chow group stars anymore
created menu-entry for showing groups and adopted slightly different icons for create_group and create_star
posts relationship on stars only contains active stars now
Changed PageManager to return a dict instead of a list containing the css-classes and stars
refactored PageManager to new subclass design and started porting create_star to use this
changed page definition from list to dict and adopted create_star and universe to use this
renamed content to star
Refactored PageManager to do the page layouting instead of using subclasses. This way we avoid Boilerplate code instantiating tons of PageManager minions.
refactored views.py to use on PageManager instance
PageManager now reaturns Page instances instead of dicts. OOP for the win!
Fixed create_star macro not using css_class
ported group page to new PageManager
All group pages use PageManager now
