Zac 6a569bbdd7 TextEditor: Change cursor behaviour when clicking empty space ...

When clicking empty space (beneath any used lines) in the TextEditor,
the cursor would jump to the start of the last line, rather than the
correct column, or the end of the line where appropriate. This was
because in the for_each_visual_line callback would return
IterationDecision::Continue if the clicked point wasn't in the line's
rect. Thus the callback would continue on each iteration and at the
end, would set the cursor to the default column of 0. To fix this I
added a bool to the callback's signature which tells the callback if
the for_each_visual_line method is on the last visual line. The
callback now does not return IterationDecision:Continue if
for_each_visual_line method is on the last line and the correct column
is then calculated with the line passed.
