- rename static subdirs to css and js
- move global static dir to core/static, changed
- move global templates dir to core/templates
- check comments and code style of all our own CSS and JS files
- minor changes related to the changes of template and static files
It is now possible to define a default state and to submit extra stylefiles and javascript files when defining a widget in an app. This is done by a new metaclass in openslides.utils.dispatch. Also fixed some other tests.
