Fix hotkey conflict in utils de.po and id.po
This is needed to catch conflicts between uppercase and lowercase
hotkeys of the same letter, as seen with (B)enannt
and A(b)lehnen
in
the german utils translations.
Also fix conflicting hotkeys in utils de.po, id.po and sv.po.
I propose this fix for all maintained branches - at least 3.0 and master, but also 2.1x if it applies cleanly.
