make Themes::ThemeFinder#clear_cache private and add some comments to ThemeFinder
clear rails asset pipeline when removing a theme
make eval code less ugly
fix typo and add some comments for ThemeFinder#register_theme
documented Theme.new_theme and changed it to take a configuration block
yep.. we need an updated Gemfile.lock
extract common code of a Theme's name finding into a method
use current_theme instead of repeating code in ApplicationHelper
shorten path_to_image code in theme.rb
Include css mixin and variables only once
Merge branch 'feature/themeing' of github.com:opf/openproject into feature/themeing
users may specify a theme in their preferences
add specs for user themes
use theme helper within ApplicationHelper instead of duplicating code
a user may now choose a custom theme in his preferences
use a translated label for user-theme
user.pref.theme defaults to application_theme if the user has not set a theme yet
