Fix typo
Change a bit in the support material, expand the support material and then substract an expanded model outline from it.
Bam! Round the boundary box in the infill generation down to a multiple of the lineSpacing to align the infill grid on eachother.
Fix MacOS compile bug.
Fixed a compiler warning in gcodeExport.h
added some wildchars to ignore
Removed some trailing whitespace in Makefile
ran dos2unix on gcodeExport.h
Set default output for GCodeExport to be stdout
ignore CuraEngine binary
made fprintf log to stderr

Made all fprintf's output to stderr so that you can easily slice a file to stdout and capture the output or push it to a pipe.  This is all for a revamp I'm doing of the unittests
Un-ingored gcode files

The unittests will be checking that gcode is output correctly, so we'll need references
Updated the unittests to check the actual output

I updated the unittests so that the output gcode matches what's expected.  Of course this all matches right now, but this means the engine can be moddified and tested accordingly.
Merge pull request #25 from grimmy/master

Random cleanups
Update Makefile to call run_tests.py $(EXECUTABLE)
use the CC envvar if it is set
Avoid a NULL pointer dereference (that clang sees)
add the gcode files that somehow got missed
use CXX instead of CC in Makefile
Simple fix for the unittests for the moment
