action 1: Package view, try and delete the package 'filled', and 'empty'.
action 2: Project view, try and delete the directory 'filled', and 'empty'.

Problem: the behaviour is not consistent, and the confirmation/warning messages are useless.

action 1 problem: no extra warning is given when the deletion will ripple and you will lose classes.

In both cases, you get a simple confirmation dialog:
"Delete package xxxx",
that doesn't tell you the 2 important things:

• 'filled' contains a class that will be deleted too
• 'empty' is empty and you won't lose anything.

action 2 problem: crying wolf/a too verbose warning is given when it shouldn't.

In both cases, you get a warning that you could lose some files
this warning is useless, as it appears even when the dir. is empty
and you won't lose anything.
