#169 Ctrl-Shit-T Should also show java classes, when using jython

[Ricardo Trindade]

When coding in jython, I think the class browser should
also show the java classes, and allow navigation to
them, based on the project's classpath, as is in java
projects.

After all, if coding in jython java libs are probably
being used, and so it's usefull to navigate to them.
