papis: Improve tui rendering and add priority maps

We render the priority of an entry in both table and multiline mode,
with priority >=1 being highest, >=3 being medium and everything
>5 being low priority.

We also have some maps for quickly setting the priority of an entry
from the tui:

`,ph` | `,pm` | `,pl` (for high, medium, low - so 1,3,5).

Lastly, I quickly added some to-dos that require the input of the
maintainer or some work in a fork, so I don't forget.
I also should not forget that I implemented some of them locally already
and am using them.
