Squashed 'tremendous/libfab/' changes from 26a0e13..581de79

581de79 More makefile cleanups * removed unused $(INCLUDE) variable usage * added -Qunused-arguments when using clang so all the arguments added   by ImageMagick don't cause warnings.
c95e2e5 Updated the readme to reflect the new porting status and add a section on dependencies
351fa9f Fix issue #14     We now use the install command to install the header, .so and .a     files Fixes the 1st item in issue #15     -I flags are now stored in $CPPFLAGS Fixes the 3rd item in issue #15     only install and clean are .PHONY
21fe772 Merge pull request #12 from rossdylan/feature/images
44015c9 Changed test.c to no longer hard code an image test path, the first argument to it will be read as an image now
bb74aaa Expose xterm_to_rgb publicly so anyone can use it, as per issue #8
ae1ba7d Merge pull request #11 from msoucy/feature/images-const
a88e84d More const
6b9c439 removed the call to MagickTransformImageColorspace which was leaking memory, and made the image look crappy
34757f4 Rename reduce_image to image_to_string, made it output a char instead of a fab_buffer_t* so the end user doesn't need to worry about it
f1878fe Only do a single realloc in append_buffer, thanks to @msoucy for pointing out that inefficency
43b651a Cleaned up some old debug code, and fixed all the warnings being output from libfab code
1d36068 No longer printf the image. The image is now built in a buffer in memory. * Auto expanding buffer implementation in buffer.c * Modified Makefile to build buffer.c * Changed test.c to free allocated memory and use the new fab_buffer_t
31adfbf Updated test.c for the new apply_color api
232cfcc Fixed a mistake, this will now actually compile
e23606e added a test c file
b1aafe6 Rough first attempt at porting the image drawing code. A lot of this is ripped almost directly from fabulous which made it pretty easy, hardest part was figuring out imagemagick.
