Typo Fix
Re-engineered the windows kitbuilding process to produce a standalone 
executable (in a similar process as tcltest is made).

The kit specific functions of tclAppInit have been wrapped around define 
macros, and are only active if TCL_KIT is defined. (Which is only done
when building the tclkit executable)
Adapted the Unix startup process to ifdef out the KIT specific behaviors.

tclkit is now build as a standalone exectuble.
