Keyboard short-cuts to set false positives

For efficient usage of setting false positives, we need a keyboard short-cut.

The short-cut will be always active for the currently selected segment. If a segment is open for editing and the cursor is placed inside the segment, the short-cut will be open for this open segment, independent if another segment is selected in addition.

The short-cut will be

• "Alt Gr" +  1
  for the first AutoQA error listed in the right side panel
• "Alt Gr" +  2
  for the second AutoQA error listed in the right side panel
• etc.

To make sure, that the order is intuitive for users working on languagetool errors and term check errors inside the currently selected segment, those are always listed first in the right-side column and they are listed in the order they appear inside the segment.

The short-cut should be shown in the right-side panel as a tooltip on the checkbox and the text of a AutoQA error, in the translate5 keyboard shortcut list.

In addition  the tooltip on the window that appears on right click on an autoQA error outside of the opened segment should reference to the tooltip by adding this sentence to it:

DE: Tastatur-Shortcut siehe Tooltip rechte Spalte "Qualitätssicherung"

EN: Keyboard shortcut see tooltip right column "Quality Assurance"
