Fixed a long standing bug related to international characters.

This bug occurred because whenever the "git blame" command detects
international character it outputs a string escaped character string in
the form "\ddd\ddd". Gitinspector didn't properly handle this. Python
offers a way to decode this using the decode function together with the
"string_escape" encoding.
