Improve the mobile css (#180)

* Better calendar css

* Change day of month to be zero-padded

* Fix list page and settings page

On the List page:
- Timespans now can collapse when the page is < 550px in width
- Moved the notes button to the far right side

On settings page:
- Removed the min width, this makes it fit nicely on mobile

- Made the chips possible to go onto multiple lines, since otherwise
long tag names would overflow (even on desktop)

* Further improve list page

The changes here also improve the calendar when you click on a timespan.
Previously it would be offscreen on my phone, and impossible to click
the 3 dots to show more.

* Remove min width on the other pages

This doesn't full fix the sizing, but it helps greatly and should be
good enough. I cannot think of any better way of improving these pages
for mobile.

* Reorder the time picker layout; Open picker in dialog

* Move notes button into menu; Move 3 dots into top right

* Fix shifted label; Removed unused stuff

* Fix lint error
