Added support for double/triple click+dragging.
Now double-click+dragging automatically snaps both ends to word boundaries (unless on series of spaces), and triple-click selects whole lines. As a side effect, snapping now occurs on button press, not button release like it previously was, but I hope that won't be inconvenient for anyone. Signed-off-by: Christoph Lohmann <20h@r-36.net>dev
