[osgeo4w-dev] pkg-shell: 2 new PATH utilities

My earlier message was wrong, addpath is used by setting a variable first:

set _path=%OSGEO4W_ROOT%bin
call %OSGEO4W_ROOT%\bin\addpath.bat _path
set _path=

I'm not sure why the author uses that method when passing the actual 
desired path would be more straightforward, from a user's point of view. 
However as I don't understand everything the file does I'm not going to 
mess with it just yet.

The above is now part of pkg-shell v 1.0.0-9, which has been tested and 
works on my machine. I promoted it to regular use. More testing and 
feedback welcome.
