dealing with strong parameters

Conflicts:
	lib/surveyor/parser.rb
more strong parameters
RIS required updates for Strong parameters support
eiacuc strong_parameters changes to surveyor gem, in progress
First pass at updating strong_paremeters to be compatible with RIS
updates is complete.
More strong params updates.
Removed attr_accessible from all models.  It doesn't
play nice with strong parameters and we don't need to support Rails 3
pre strong parameters after this.
