Support encoding="utf8" in build

[Bill van Melle <billvm@…>]

I want to be able to include utf8 characters in my .java files. To that end, I have set the default file encoding in Eclipse to utf8, and this works fine for editing files and building within Eclipse. But if try to package things up with build.fxbuild & ant, I get gibberish. I can manually edit the build.xml file to put encoding="utf8" in the javac element, but I don't want to have to do that every time. So either the builder should respect my default file encoding, or there should be a slot in build.fxbuild for file encoding.

the project encoding is now used for the javac-command
