Internal yielding for sensor calls, magic sensor card, turtle fix.

This pull request changes the sensor API to essentially just be another name for the peripheral API to allow for backwards compatibility with existing programs, due to moving the yielding and waiting for the event into the java side of things.  This vastly simplifies the user experience going forward, and is in line with the current turtle API in ComputerCraft.

This also fixes the turtle sensor cards.  The gauges remain to be fixed.  This pull request also enables the magic sensor card.  Thaumcraft support has been tested and seems to be worked.  AM2 support is included, but has not been tested.
