Adding capability for running codes directly from gct files about sneek HOT 4 OPEN

If you fix your code (add IOS_Close) I could give you commit access if you want 
to.

Many thanks for your feedback and for giving me the opportunity to add/commit 
this into the repository. I will definitely add IOS_Close( fc ) in the section 
of opening and reading the gct file. And should I also help doing the same 
thing for the section of opening and reading kenobiwii.bin file {i.e. IOS_Close 
( fd )}? Just to be sure. Cheers.

I gave you commmit access, please keep my coding structure.

This is the updated patch for r168 that I will use to modify the file dip.c (in 
DI folder) which now uses the DVD instead of IOS functions for working with the 
codes file (otherwise sneek+di cannot open/read the codes file).
