remove minor convenience feature and rename a function in hitme to (maybe) fix random failures
fix <pre> inside <pre> double scrollbars
fix ace editor for combine step
more randomization for hitmes
fix comments with multiple entries not being listified properly
description update
more space per column
implement split layout for all hitmes.

Previously only used for the inputs/comments in final check, it
is now used for the job description and metadata as well as
the input/preview on typing, proofreading and combining. Also,
all pages now autosize the comment field.

This should allow for a better usage of current screens, as long
as about 1000px in width are available.
fix tests
fix bug where final came before combining (+test)
