Create KitDLL -- libtcl that includes VFS

<hr /><i>rkeene added on 2010-09-30 09:39:47:</i><br />
Added KitDLL support as of [2dbaa7246a].

package require vfs::zip  is failing

<hr /><i>rkeene added on 2010-09-30 09:40:34:</i><br />
Need to add some way for users to update the VFS without recompiling/relinking the DLL
