[Mono-dev] Compatible dll's

I am trying to optimize compile time. Unity splits compilation into a couple
of different dll's, depending on which folder the scripts are in.

Compilation is started whenever a user saves a script. Once a dll has
finnished compiling, all dependent dll's need to be compiled.
I would like to avoid compiling the dependent dll's whenever it is possible.
Simply because short compile times make our customers happy.

So my idea was to detect if the signature of the dll we compiled against is
the same as the one we will now replace it with. If the signature is the
same i can simply skip compiling all dependent scripts, thus save a bunch of
unnecessary compile time.
