Yeah. This needs to be solved doesn't it.
Solutions:
Make replace accept \n as being a newline. This would be doable, but what
if someone wanted to replace a \n sequence? Is it acceptable to make
'tabs' illegal in the replace etc. Probably not.
Add a replaceJava attribute, for specifying the replace tag as a Java
attribute. Would want a withJava attribute too.
Or maybe this is an encoding="java" attribute.
Have a replaceNewline tag. A bit weak as you won't be able to replace
something with a newline in. Also has weaknesses as I'm trying to collate
similar functionality and not create more tags.

I seem to recall that there are no XML character entities that work
there, but possible I could make one work. Whether this would be
cross-server though, I don't know.
Most people will want \n to work I imagine, and won't care that they have
to do \\n to replace a \ and a n. If I change it so that all
String attributes get unescaped for Java entities, and maybe even all
content as well. I wonder if this will hurt anything...
If not, I'll aim for this feature to be in a 2.0 release. My apologies for
not being able to get it in sooner.
