Pid fix
Moved src/drivers/machines -> src/machines
Merge pull request #35 from Wallacoloo/devel

Moved src/drivers/machines -> src/machines
Update path changes
Fixed #33 (Move Event -> OutputEvent translation into the State)
Removed outdated 'canDoPwm' function.
Machines are no longer in the drv namespace
Machines are now placed in a folder hierachy based on the platform and must use qualified path in make (eg make rpi/KosselPi)
now make MACHINE=rpi/KosselPi' are interchangeable
Can now detect rpi targeting from MACHINE name, not dirty uname hack
Removed dead code
Added experimental support for using DMA with only pins 0-31 (more efficient)
Fix not using rpi-specialized routines when compiling for rpi
Remove inclusion of typesettings.h (replace with smaller components)
Revised typo in DMA optimization
