BioNetGen 2.8.0 appears to change the case requirements for states

[jonrkarr]

Example: https://github.com/biosimulators/Biosimulators_test_suite/blob/0.1.84/examples/bngl/Dolan-PLoS-Comput-Biol-2015-NHEJ/Dolan2015.bngl

• This works with BioNetGen < 2.8.0
• 2.8.0 produced the error log below
• For 2.8.0, I needed to change the PLUS and MINUS states to Plus and Minus (see changes) to avoid these errors.

Error log:
You are trying to give a pattern of type 'Sen', but you gave an 
invalid state! The state you gave was: 'PLUS'.  Quitting now.
You are trying to give a pattern of type 'Sen', but you gave an

I'm post this here in case this wasn't an intentional change.
