r513:
- Addressed the following code review items, courtesy of Dean Hall, with one 
modification: rather than change pmImgCreator.py, this version provides the 
full-featured VM with all the #defines enabled

415     docs/src/HowToPortPyMite.txt:54     Remove the question in the

comment
445     src/tests/system/Makefile           THANK YOU for fixing this!!!!
461     readme.h                            I would like to get rid of readme.h 
if possible to eliminate redundant text.
510     src/lib/__bi.py:904                 Move "NATIVE_SET_TOS(PM_NONE);" 
after the #endif, so None is on TOS.
511     src/tools/pmImgCreator.py           Do not merge these changes.  *(1)
512     src/tools/pmImgCreator.py           (same as 511)
====    =================================   ====================================

(1)     The workaround for this situation that I've been using is to make a
       patch file using "svn diff", put the patch file in src/platform/pic24/
       and create a "make once" rule in pic24/Makefile to apply the patch.

r518:
Resolved three issues found by Dean

src/platform/pic24/pyFuncsInC.c:1752
   Can a non-py form of this function be called from within plat_init() to
   avoid a py wrapper?  Doing so would save some heap.

Resolution: converted vars to #defines and eliminated the need for initXxx 
functions

src/platform/pic24/plat.c:76
   Consider disabling the Timer2 interrupt in plat_deinit() so that
   pm_vmPeriodic() isn't called after the VM exits.

Resolution: disabled timer interrupt

src/platform/pic24/pyFuncsInC.c:88
   configDigitalPinPy() calls CHECK_NUM_ARGS(6), but its python wrapper,
   digital_io.__init__() (src/platform/pic24/pic24_dspic33.py:64)
   accepts a variable number of args (4-6)

Resolution: now accepts variable args, default args
