v0.4.0

• Fixed pinch gestures not being able to have the 'any' direction.
• Update actions now always repeat. If the interval is 0, the action will trigger exactly once per input event. If it's not 0, the action can trigger 0 or multiple times, depending on the delta.
• Added the input action, which allows for pressing mouse buttons and moving the cursor, in addition to pressing keyboard keys. The keyboard action functions as before, but it's now deprecated and may be removed in the future.
• Swipe gestures can now have the any direction, although this isn't implemented properly yet, as thresholds and intervals still only apply to one axis.
• It's now possible to create a drag window gesture. See example gestures.
