I like this change in header include structure.  Most of the projects I work on 
do it this way, and it makes a lot of sense.  Because this will be a change 
that impacts just about everyone doing C++ development using GNU Radio, I think 
-if possible- it would be good to keep the "gr_<name>.h" headers around, but 
all they do is 2 things:

1) print out a #warning about being deprecated, and to instead use 
"blocks/<name>.h" -- or, whatever makes sense for such a message; and

2) #include "blocks/<name>.h" so that the user's code still compiles as before

That way, we benefit from the new header include structure, but aren't totally 
screwed if we've forgotten to use it.  And, somewhere down the road after an 
appropriate amount of time, the "gr_<name>.h" headers can be removed entirely, 
if desired, because everyone has been well warned.  I hope something along this 
line can be done.
