[PATCH v2 2/4] vbscript: Move the script context heap to the script dispatch object.

[Gabriel Ivăncescu]

Just a quick update. After further investigation and tests, it does seem 
like my assumptions were correct, so now I'm looking for the best way to 
make the relevant changes. (this does mean we'll have to move some stuff 
to the script dispatch though, and it will be necessary when we make use 
of the pstrItemName arg anyway).
