LibGUI: Add flag to TextDocument's word break locator methods

Browse source 
TextDocument::first_word_break_before was refactored out to be able
to be used in multiple places throughout the project. It turns out
that its behaviour needs to be slightly different depending on
where its called, so it now has a start_at_column_before flag
to decide which letter it "thinks" was clicked.
