core: Fix button action with multiple conditions not firing (fix #195)

If a button event had both a keyPress condition and another
condition:

on(release, keyPress "A") { }

these actions would not fire on click, because it would still
check if the key was down (which doesn't apply to clicks!)

Fixes #195.
