catkin_make_isolated does not output catkin version

[tkruse]

catkin_make does by default.
That would help for debugging user problems.

also catkin_make_isolated should get --version option

-1 on adding a command line argument like --version``. I would propose that catkin_make_isolated should be default print the CMake and make output (as it does with --verbose). Instead there could be an option--quiet` which hides the output (as long as there is no error) as it is currently done by default.

To be clear, CMake outputs the catkin version not catkin_make.

I would be fine with either defaulting to verbose output (so you can see the CMake output for each package which contains the catkin version) or having catkin_make_isolated output the version explicitly. Either way there should be an easy way of detecting the catkin version without invoking CMake, so maybe we should set that up.
