Add a command line argument to filter/limit the archetypes returned by mvn archetype:generate

Currently, running mvn archetype:generate returns 390 archetypes, on my machine.
By default, th window buffer of my terminal isn't set big enough so I can see the first archetypes in the list.

So, I think it would be really useful to have a CLI arg allowing us to filter the archetypes containing a string.
Ex: running

mvn archetype:generate -Dfilter=webapp

would return only the archetypes having webapp in their artifactId.

What do you think?
