Ant 1.6 support

When I add 'description' attribute to a property, IDEA hilights it as
structural error which is clearly not the case.

When I import antlib using ]]> task, IDEA doesn't recognize the
imported tasks and namespaces (build compiles fine though).

I cannot see the ant javadoc anymore. I've tried to set my custom ant,
but no luck. I remember it working at some time, but now all of a sudden
it doesn't.

Also I'd like better support of macrodef's, namely first-class treating
of attributes and elements.
