[Flashforth-devel] PIC18 1.1.2018

Hi Peter and all,

The ff51 branch was merged to master today.

The biggest change is the way the return stack is managed.
FSR2 is used as the return stack save pointer in task switching
and for R> >R R@

the return stack buffer.

It can only be used for temporary data storage.

Another change is that PAUSE skips the task switch if there are no 
background tasks to be run.

Therefore the newest versions of task.txt and doloop.txt must be used.

A more complete table driven SEE is included.
