Obviating init.tcl

Whenever [interp create] creates a non-safe interpreter, it goes
through a quite costly initialization process potentially involving
regexps, file system access, $env access - all to source a file
init.tcl which is around 850 lines of tcl.

That's *every* time.

That's a lot of overhead which may be obviated in some cases.

I have two alternatives:

1) expose the C variable tclPreInitScript to tcl, enabling tcl scripts
to avoid the init.tcl process.

2) add a -minimal option to [interp create] which skips all the default
stuff.

I imagine this would make [interp create] a *lot* more lightweight.
