Big fix just went in for property specific. Mask calculation is now
fully determined at network build time, and not runtime. Much greater
test coverage for various network build configurations. Lots of edge
cases are now fixed as a result of increased tests, and also ability to
test at build time, rather runtime. Rule removal is now supported and
masks will be recalculated.

Cell() Will not listen to any changes without adding an a @watch; i.e. a
pattern without any constraints is equivalent to @watch(!*)
With regards to @PropertySpecific. I'm now leaning towards the following
two:
ClassListener
PropertyListener
Which is short for:
ClassChangeListener
PropertyChangeListener
I don't think we need the longer version as it should be pretty clear
what the shorter versions are. The names are very generic, so we just
need to be sure they don't clash with other potential annotations.
The above two require no attributes, but must be used exclusively. The
alternative is:
ChangeListener(Property)
ChangeListener(Class)

yup, we are struggling to find something that is consistent and
doesn't look pants :(
So far we just keep coming back to PropertySpecific, which is ok for
now. But once we reverse the behaviour with the common use case
becoming PropertySpecific(false) we lose a little bit of language
ergenomics imho. Btw I say common use case, because PropertySpecific
with no arguments won't be useful as that will be the default
behaviour at that point.
