[support] How to know the Source of a Block

[Fred Jones]

There is one thing that drives me crazy when working on a large site 
that I didn't build and that is that there are a bunch of blocks in the 
block list, one called 'events_calender' for example. I can't delete it 
so I know it's not a custom block. But I can't find it in the module 
code anywhere, so eventually I realize that it's a view.

It would be helpful if there was a note next to each block saying what 
the source is, whether module or view. If this is an intelligent 
suggestion, let me know and I could suggest it. If it's not, let me know 
that too. :)

Thanks.
