Make hints easier to discover

[carnager]

It would be very handy if hints were visible in the week and day views.

Right now it's impossible to see if there are hints for a specific day. Neither the weekview nor the detailed view of a single day have any indicator for present hints. If one wants to use hints for e.g. documenting reasons for starting work late/leaving early this is not very useful in the current state.

So I propose to add a column for weekview to let the user know that there are hints set for that day.
Also add a column in details view for the day that also shows an indicator. (Or even the content, if space allows it)

there could be a reserved space at the bottom half of the screen. if an entry is selected, show details of the entry, including the hint.
Optionally the indicator could show the actual content of the hint, if it's short enough. (e.g. "-0:30" if one worked 30 minutes less)

If the IN and OUT columns in weekview could be squeezed a bit (they are far wider than needed right now) this would easily make room for another column that shows an indicator for hints.
