This commit does a few things to modulecmd.tcl
This commit does a few things to modulecmd.tcl

It cleans up some unused global vars
Fixes some spacing in some report statements
	as well as fixes some debugging statements
adds a ubuntu specific bit of code to uname
	so uname release returns the codename of an ubuntu install

Finally in getPathToModule
I commented out the Check for aliases bit of code
This is already done at the top level so no need to do it again.
(If someone finds a case where this is needed let me know and I'll
add it back in)
