\brief Updates the font family list
\param check_only If true, the function only checks to see if the font list has changed
\return true if the font list has changed, false if not.
Because of the differences in the R5 and OpenBeOS font subsystems, this function operates
slightly differently, resulting in more efficient operation. A global font list for all
applications is maintained, so calling this function will still be quite expensive,
but it should be unnecessary in most applications.
