Turning off the FORCE_LONGITUDE_FIRST_AXIS_ORDER as a global default 
allowed the epsg-hsql authority factory to be discovered.

Martin are you still interested in breaking apart the "service 
discovery" use of factory spi form the management of factory instances? 
Right now we are asking FactorySPI to pull double duty - something I 
don't believe it is set up for ... witness the amazing lengths we go to 
to make a no argument constructor available (for discouvery) along with 
a constructor that accepts some form of configuration (in the forms of 
Hints).

I am willing to write up a change proposal to this effect.
