Fixes

Closes #423

See merge request !3358

There are computations involved for some of the table cells, that might
result in long decimals. It makes sense to round them to 2 decimal
digits (the way money are formatted). Other cells are formatted in this
way to unify the look.

Refactor slave buying links into a widget and move the decline link to the top

See merge request !3342

Refactor identical link stuctures from markets and schools into a couple
of widgets and move the decline link to the top as that prevents
accidental clicking the buy link when browsing a market and the decline
links is the only one among them that is always available, so the new
layout creates less text jumping.
