Re: parsing variable name in a velocity template

Put the Velocity context in the Velocity context.  Then use the getKeys
method to get an array of all the context keys.  Check the javadoc for
this at http://jakarta.apache.org/velocity/api/index.html.

It is possible to have $something in a template without it referring to
any context field, so regex won't work in all cases.
