Fix for broken touch handling (move/press/click on mobiles)

[pludov]

Was broken by recent refactor (seem my last comment here: https://github.com/slowe/VirtualSky/commit/a43ab2383cca145083c8fc1703fd36ad4e69f7ba#r34608949 );

This new touch handling code differentiates click/long click and move for press events.
