Refactor|libgui|Client: Untabbed lines among tabbed lines
It is now possible to set the tab stop to -1 to indicate that the line should not be tabbed at all. The objective is to allow reseting the tab stops within a longer piece of content, continuing with a new set of stops.
Refactored FontLineWrapping and GLTextComposer to allow processing tabbed lines in distinct ranges.
