Subject: [PATCH] Untangle: fix redraws when dragging with cursor keys.

The recent addition of graph editor functionality to Untangle in
2ac951e broke redraws while dragging a point using the cursor keys. In
particular, the new ui->dragtype field was not being set by the cursor
dragging code path, causing redraws to erroneously exit early.

Generally, there is quite a bit of code duplication between the cursor
and mouse dragging code paths in interpret_move(). Some refactoring
could perhaps reduce the chances of this happening again.
