EXPath Binary module: bin:unpack-integer()

A minor change (suggested by Christian Grün) is proposed to the Binary 
module:

    renaming  bin:unpack-signed-integer()   to bin:unpack-integer()

on the basis that XPath integers are signed by default, and will be in 
line with bin:unpack-float(), bin:unpack-double(). 
bin:unpack-unsigned-integer() remains with the same name.

'Last Call' for changes to the Binary module will be issued soon (before 
it progresses to the dizzy heights of being the first EXPath '1.0' 
version), and as far as the editors are concerned, this is the last 
substantial change. Any objections to this - please holler...
