This adds some auto-closing code to the scripting API of the CFile
system. If a file has to be auto-closed then an error will be displayed
to let the the script writer know that something is wrong.
This should not break existing scripts since causing file handle leaks
should never happen and if it does, this will make it easier to find
these issues.
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
