encoding support for internationalization

Hi,

Current QDox doesn't support encoding. I want qdox to support encoding to improve internationalization.

I wrote patch for QDox and I uploaded here.

http://yamaguch.sytes.net/~tora/tmp/qdox-encoding.patch

Please take it.

Then QDox support encoding with following code:

JavaDocBuilder builder = new JavaDocBuilder();
builder.setEncoding("euc-jp");
builder.addSource(...);

reagards,
