Those are heavy changes concerning the Binary Parser.

Browse source 
The problem was that binaryParser scheme was
a perfomance problem affecting a lot of people
when projects were medium/big size.  The IBinaryParser
was extended to allow one more method isbinary()
so that will let the BinaryParser open() the file
only once instead of multiple time like it did before.

Attempt to address performance problems from the binary parser
on big projects. The problem is that files are open multiple
times to detect if they are binaries or archives. We can
not really rely on the filename or extension. A new method
as been added to the IBinaryParser interface, isBinary()
taken an intial byte[].
