[fix] reset position.start on touchstart and touchmove
Merge pull request #1 from Lulo/skip-page-fix

Skip page fix
Ignore velocities if they're zero, Android is sending duplicate events. Change hard coded speed to use the param.
ensure el.className is a string before calling indexOf. el.className is an object if el is inside an svg
To calculate velocity, keep an array of all move events then use the oldest one up to 150ms old to calculate velocity. This prevents stop-then-release from having momentum.
