xslt Task

[Fotis Jannidis <Fo...@lrz.uni-muenchen.de>]

The Fop project, part of xml.apache.org, needed a xslt task. As there was the proposal 
to build up a repository of such additional tasks - probably the best solution to avoid 
bloating Ant and at the same time providing an easy access to building blocks - I post it 
here. 
It only implements the 'smart' attribute which was proposed on this list, so it checks the 
existence and date of the output file, but it has no additional attribute where you can list 
other dependencies.
