#32 ES_EXPORTTITLE support.

[Anonymous]

Please implement support for the ES_EXPORTTITLEINIT, ES_EXPORTCONTENTBEGIN, ES_EXPORTCONTENTDATA, ES_EXPORTCONTENTEND, and ES_EXPORTTITLEDONE functions.
Thus almost completing the very useful es library.
It's mainly to combat the age old problem of not enough system memory, by backing up titles onto SD or USB.
Seeing as the backed up titles would only work on the console they came from I can't foresee this causing any problems...thank you.
