smb:// support in InceLibrary2

Changed access to files to use xbmcvfs instead of standard file access (except for local/config files). I've tested it using smb:// to access a NAS and it both created files and directories, and removed them. 

Also made a quick fix to the update of the autoexec.py in order to use RunPlugin instead of RunScrip to go around bayfiles error in urlresolver. I do not know if this is the best approach so I left the previous code commented out to let dudehere decide what is the best approach.
