test updates

- update main love readme to include note on tests
- added module tests for Sensor, Keyboard, Touch, Joystick, Mouse, and Love (for hooks + basic love-level methods)
- general clean-up of main class logic
- couple fixes for runner-specific failures (physics.Joint, audio.getActiveSourceCount, mouse.getPosition)
- change window.close test to run last
