verbose mode for modulel testing

[daviddelikat]

add an option to run tests without Test::Harness/summary so that the user can see all the output. -- makes debugging a single module much easier.

Any parameters to the test command that aren't handled by WGDev itself are passed on to the call to prove. So you can use the -v/--verbose option to get all the output, and -m/--merge if you want to make sure STDOUT & STDERR are properly synchronized.
