Merge pull request #41 from caitp/caitp-work

Added a standard webvtt-config-win32.h for win32 builds, and modified include/Makefile.am to install it if needed
Added changes to function signatures to indicate whether they are exported (visible in shared library) or 'intern' (not visible, which seems to be needed for any non-static functions when built with GCC 4.0+) -- Also, some work on the unit test stuff
Delete test/unit/libwebvtt.dylib
Delete Makefile
