Lots of FS HLE fixes and implementation of missing functions/objects. (#24)

Browse Source 
* 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
