Add support for JBehave step variants.

[dschneller]

Changed jbehave-core to version 3.6-SNAPSHOT as of 2012-01-20.
This version contains http://jira.codehaus.org/browse/JBEHAVE-702
and allows several variants without having to resort to aliases.

This change adds support for these to the Eclipse plugin, for completion,
highlighting and error reporting.

Thanks for your change!

I'm just wondering how to get a "stable" version of jbehave 3.6-SNAPSHOT
Since it is not used to effectively run the tests, i guess the "stable" criteria is not really mandatory... I'll merge your pull once i found time to build and commit the jbehave-core-3.6-SNAPSHOT.jarlibrary.

I'll probably do it this week end.

That's what I thought, too. I contributed the variants patch to jbehave and would like to use the plugin in a customer project. I wouldn't hesitate to use a snapshot build of the plugin, if you want to wait for 3.6 stable, but an "official" one would of course be easier to sell :)
