Instead of doing it just for the Information tab, do it for all of the tabs.
There's still room for improvement. But this certainly feels more consistent.

Most tabs in the dive-information widget have there own translation
units and ui-files. Only the equipment tab was married with the
main tab. Move it out to get more reasonably sized translation units
and some isolation.
Currently, this needs ugly hacks when entering / checking for edit
mode: Access to MainTab is via the MainWindow. And vice/versa, when
accessing the DiveEquipmentTab from the MainTab, the former is
hardcoded as the first item of an array.
These hacks will soon be removed though, when making equipment
editing undoable. The tabs will then be independent.
