programs/wcmd: wcmd-1

["Jaco Greeff" <jaco@puxedo.org>]

Hi,

This small change to wcmd allows us to use "wcmd /c <command>" from other
applications. Basically, it skips the initialisation of the console and uses
the current STDIN and STDOUT handles for output instead of allocating a new
console which will return immediately. 

The benefit of this is that we can pipe commands to and read piped output
from the interpreter.

Changelog:
* programs/wcmd/wcmdmain.c: Jaco Greeff <jaco@puxedo.org>
- Skip the allocation of a new console on "wcmd /c <command>" execution,
using the current allocated STDIN and STDOUT handles for command input/output
