Figured out why selector wasn't working

Now I need to make the megapanel modify pressure change values when a
selection is made.
Needles now switching direction

However, the megapanel won't turn off.

Explosion still broken.
Megapanel working again! \o/

Now to tackle the lose condition bug.
Player sprite draws in Phaser
Player moves back and forth

But it’s not pretty! xD
Created InputHandlers namespace

Refactored out Input-related functions from main_stage update()
function.
