- Add new touch device type enum ("touchscreen", "touchpad", "touchpadrelative"). Coordinates for touchscreens are window-relative DPI-scaled pixels, and coordinates for touchpads are normalized [0, 1] values.
- Add new devicetype enum and ismouse boolean params to touch callbacks.
- Add love.touch.getDeviceType(touchid), love.touch.isMouse(touchid), and optional device type filter param for love.touch.getTouches.
- Add t.trackpadtouch boolean (defaults to false) to love.conf. Trackpad touch events will not be generated unless it's enabled.
Currently the trackpadtouch setting only works on macOS.
Resolves#1633.
Resolves#2093.
- Type names for love's Lua objects are specified as an argument to luax_register_type, rather than being statically defined in an array.
- luax_register_type takes a variable number of method array arguments, for registering superclass methods without copying them into the subclass' method array.
Also removed most of the header declarations for wrapper functions.
love.touch.getTouchIDs returns an array of all currently active touch IDs. love.touch.getPosition takes an active touch ID and returns the current position of that touch.

Note: this implementation is slightly different from the implementation in the love 0.9.x Android and iOS ports!
Added love.touchpressed(id, x, y), love.touchmoved(id, x, y, dx, dy), and love.touchreleased(id, x, y, dx, dy).
id is a unique identifier for the touch press that persists until love.touchreleased. After that it is no longer unique.
x and y are the coordinates of the touch event in pixels within the window.
dx and dy are the amount in pixels that the touch has moved since the last event.
Added love.touch.getTouchCount and love.touch.getTouch(index).
love.touch.getTouch takes an index (not the same as an id. indices are not stable and don't correspond to a unique touch press.)
It returns the id of the touch and its current x and y coordinates in pixels.
