UI rehaul

[L7R7]

Right now the UI is everything but fancy, but with my limited CSS skills it was the only way I found that fulfills all my requirements.

Requirements for the UI

• Basically, I'm looking for a layout with tiles that are squares
• Instead of resizing the tiles, the tiles should be rearranged on different rows and columns if possible (that's something I quite like about the current solution)
• The whole tile should be clickable, not only the text
• The page title (and maybe the favicon) could represent a summary of the build statuses (for example the UTF-8 checkmark when all pipelines are green or the number of broken pipelines if there are any)

Some ideas that sound good to me

• I'd like to have a bootstrap based UI. I kinda like the cards that it offers: https://getbootstrap.com/docs/4.0/components/card/
• I definitely prefer a very simple UI that ideally doesn't need any JS. Maybe it makes sense to add something that reloads the data regularly, but for now I found a JS-free way that works
• It would be nice to have some kind of footer at the bottom that contains metadata, like the timestamp of the last update

Since 338415dc0a739107a5a018321ecfed23967a3de9, the status is not shown as text anymore. Instead, the color of the tile and the Tooltip indicate the current status of a pipeline.

I like this, because it's cleaner and less clutter now

The tiles are (pretty much?) quadratic now, done in eb11e7f4ffe814536ab34da78d94b7b13e97e610. Closing this for now
