Enable the terms "release" and "feature" to be defined within a product

Now that  I've started using Aha for the product plan, other areas of the organization are asking if they can use Aha for enterprise project planning.  It looks like a "release" could be considered a "project" in their terms.  And a "feature" could be considered a "task" under normal project planning tools.  Enabling them to rename "features" and "releases" would help them understand how they could best use the tool.
