[chuck] (win32) type checker crash fixed

[Ge Wang]

Dear All,

(win32 version only):

There was a bug in the type checker where it would crash
on calling functions in namespaces like std.rand( 1.0, 2.0 ).
(wrong # of arguments and type should be int)

The correct behavior is to (not crash, first of all and) return
meaningful message that it doesn't fit the prototype.

This has been fixed and will be in the next release.  In the
meantime, there is an updated chuck_type.cpp and win32
executable:

     http://chuck.cs.princeton.edu/release/snapshots/

This doesn't seem to affect other platforms (we are tracking
down why not)  Thanks to ./rrm and Mikael for finding this.

Best,
Ge!
