Draft: Adding a v1

Goal of this PR is to get the talp-pages into a state in which we can release it to pypi.org. Therefore a few things still need to be done:

• write some simple tests to catch all the "oh no, this class hasn't this method problems" just calling the classes with mocked databases or something
• Style the whole thing better (boostrap v5?)
• Add Documentation
• Maybe merge the gitlab CI things into this repo?
• ?

@jvinyals and @vlopez I will request a proper review of my code once I consider this not a draft, but if you have any comments please shoot already :)
