Added the FindFreetype.cmake CMake module, set the minimum require CMake version to 2.8.3 and fixed the paths to the FreeType headers.

+#
+# $FREETYPE_DIR is an environment variable that would correspond to the

+# Ugh, FreeType seems to use some #include trickery which
+# makes this harder than it should be. It looks like they
+# put ft2build.h in a common/easier-to-find location which
+# then contains a #include to a more specific header in a
+# more specific location (#include <freetype/config/ftheader.h>).
+# Then from there, they need to set a bunch of #define's
+# so you can do something like:
+# #include FT_FREETYPE_H
+# Unfortunately, using CMake's mechanisms like include_directories()
+# wants explicit full paths and this trickery doesn't work too well.
+# I'm going to attempt to cut out the middleman and hope
+# everything still works.
