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.
added a test c file
Fixed a mistake, this will now actually compile
Updated test.c for the new apply_color api
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
Cleaned up some old debug code, and fixed all the warnings being output from libfab code
Only do a single realloc in append_buffer, thanks to @msoucy for pointing out that inefficency
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
removed the call to MagickTransformImageColorspace which was leaking memory, and made the image look crappy
More const
Merge pull request #11 from msoucy/feature/images-const

More const
Expose xterm_to_rgb publicly so anyone can use it, as per issue #8
Changed test.c to no longer hard code an image test path, the first argument to it will be read as an image now
Merge pull request #12 from rossdylan/feature/images

Feature/images
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
Updated the readme to reflect the new porting status and add a section on dependencies
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.
