Subject: [PATCH 1/5] fixed getPointer & drag functions for touch screen

getPointer and drag were not setting position when using a touch device.

This quick fix may not work properly when using multitouch but I didn't saw any problem on chrome emulation and on my phone.

There is multiple ways to get the touch event's position and I might not use the best one. Maybe someone with experience in the matter could improve this solution?

Subject: [PATCH 2/5] isValidDrag should ignore "tap" events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

detect ̀ ``touchmove``` instead of `̀``touchstart``` event. This way we ignore simple "taps" on screen, meant to use links, etc...
