Lots of FS HLE fixes and implementation of missing functions/objects. (#24)
* Initial pass - fixes IFileSystem OpenFile, implements IFileSystem CreateFile/DeleteFile, fixes IFile Read and implements IFile GetSize/SetSize * Implement IFileSystem Directory* methods, as well as RenameFile. Add IDirectory, and implement its Read and GetEntryCount methods. * missing TODO * hey, this is kinda bad * Update IDirectory.cs Fixed :) * Some cleanups to IDirectory, fix for OpenDirectory on a non-existent directory. * Item -> Index * This should work. * Update IDirectory.cs Marshalling version
