#432 extend editor title

[Martin Schnabel]

the editor title should optionally show the folder name. e.g. "mypackage/__init__,py"

maybe a simple preference option allows the user to opt in.

backgroud: in django all most of the filenames follow a convention. with pydev one usually ends up with tens of models.py, urls.py, views.py and admin.py files. making the editor title pretty much useless.
