Added support for official Xbox 360 wired gamepad, updated README.

Hello again @vikashplus

Thanks for the tip in #2 , managed to get it work by installing the missing inputs dependency.

This PR adds

• a section for dependencies install, as well as support controllers.
• gamepad.py now supports the wired Microsoft X-Box 360 Controller
• Analog stick and trigger values were changed from discrete to (normalized) continuous values, allowing a fine grained control of end effector during tele operation.

Tested the changes with robohive;s ee_teleop.py script. Unfortunately I could not test with the default "Logitech F710" controller, but I am pretty sure it will still work since I only added additional buttons and triggers for the X360 controller.

If case you are open to it, I could also do a PR on robohive's tutorials/ee_teleop to add the polling function for the gamepad.

Hope this can be useful down the road.
