Maven Resource-Filtering Escapes Backslashes

Having moved up to Maven Resources Plugin 2.3 in order to stop Maven from attempting to filter some binary files for us, and in so doing, destroying them, we've discovered that 2.3 has its own problem -- it escapes backslashes and colons in files where escaping is totally unwarranted, which does a surprisingly good job of destroying an XML file we need for Selenium and Java Web Start to play nicely together (a mimetypes.rdf that tells Firefox how to deal with a JNLP file).

Three cheers for Maven, an ecosystem of tiny plugins, each of which has its own set of bugs and idiosyncrasies, which collaborate to ensure that there's no valid way to build your project.  Whee.
