Use UTF-8 encoding.

In the maven build we had to give special instructions to maven so that it would use a non-default code page. UTF8 is the default code page, but we cannot use UTF8 because there are a few non-utf8 characters in the project. In particular DeepDive06ModelViewController.infiniteB uses accented characters that are not in UTF8. We should replace them with UTF8 equivalents and tell eclipse and maven to each use UTF8.

Updated deep dive 06 to remove the non US-English character. We still need to fix the build to use UTF8.
