Requirement

The user should be able to resize the segment table in the editor. Identical to what CTRL++ and CTRL+- does in the browser by default, but through click on a button and restricted to the segment table.

Implementation

The buttons should be placed left of the button "Tabelle zurücksetzen". The keyboad shortcut CTRL+/CTRL- should override the usual ones of the browser and should be shown by tooltip.

To save space in the upper menu area, the buttons for switching the tag modes should be combinded into a menu-button with the name "Tag mode".
