NEqProblem fails with BFGS and LBFGS

Lines 25 to 29 in 486e562

	if !(scheme.reset_age === nothing)
	JFx = factorize(Jx)
	else
	JFx = nothing
	end

asks the scheme for a ´reset_age´ field, but there isnt one. with that, only newton works on NEqProblems. maybe using a function instead of a field access could solve the problem?

I see what you're getting at, but I think everything here should just be annotated Newton. Then, another dispatch can wrap the objective in a meritobjective type and minimize it.
