Added a new function: AddNewEvent, which only adds an event to the list if it doesn't already exist. Kept the old one as it might me useful to be able to add an event more than once.

*
* @function:
* FT_Stream_OpenGzip
*
* @description:
* Open a new stream to parse gzip-compressed font files. This is
* mainly used to support the compressed `*.pcf.gz' fonts that come
* with XFree86.
*
* @input:
* stream ::
* The target embedding stream.
*
* source ::
* The source stream.
*
* @return:
* FreeType error code. 0~means success.
*
* @note:
* The source stream must be opened _before_ calling this function.
*
* Calling the internal function `FT_Stream_Close' on the new stream will
* *not* call `FT_Stream_Close' on the source stream. None of the stream
* objects will be released to the heap.
*
* The stream implementation is very basic and resets the decompression
* process each time seeking backwards is needed within the stream.
*
* In certain builds of the library, gzip compression recognition is
* automatically handled when calling @FT_New_Face or @FT_Open_Face.
* This means that if no font driver is capable of handling the raw
* compressed file, the library will try to open a gzipped stream from
* it and re-open the face with it.
*
* This function may return `FT_Err_Unimplemented_Feature' if your build
* of FreeType was not compiled with zlib support.
