[jdom-interest] XMLOutputter Entity escaping again

[Alex Rosen]

Some of the things I was planning on suggesting/contributing once I had
the time:

- Let the user specify how to escape a character
- Support for surrogate pairs (i.e. characters > 16 bits, in Unicode
3.1)
- Using a different technique to avoid the reflection on every encoding
call when using JDK 1.4
- Get rid of the annoying duplication of code between
escapeElementEntities() and escapeAttributeEntities()
