Release v0.4.0 - Tue Sep 21 11:20:39 EDT 2004

Changes to BNF
+ Made a naming decision that this is the "new TPTP syntax (aka, the TSTP
  syntax)", and the old TPTP syntax is "the old TPTP syntax"
+ Separated out numbers and strings as special types of functions, so in the
  future they can be interpreted constants.
+ Added signs to numbers, and made <unsigned integer>
+ Removed assumption type - it is a synonym for hypothesis

Changes to Problem Status Ontology
+ Changed Unsolved to Unknown, to fit in with TPTP attitude.
+ Fixd what SatisfiabilityBijection, SatisfiabilityMapping, and  
  SatisfiabilityPreserving show about F (thanks to Larry Paulson)
