`Options` needs a clean-up

[benedict-96]

At the moment we store:

SimpleSolvers.jl/src/base/options.jl

Lines 140 to 165 in 69c6d5e

	struct Options{T}
	x_abstol::T
	x_reltol::T
	x_suctol::T
	f_abstol::T
	f_reltol::T
	f_suctol::T
	f_mindec::T
	g_restol::T
	x_abstol_break::T
	x_reltol_break::T
	f_abstol_break::T
	f_reltol_break::T
	g_restol_break::T
	allow_f_increases::Bool
	min_iterations::Int
	max_iterations::Int
	warn_iterations::Int
	show_trace::Bool
	store_trace::Bool
	extended_trace::Bool
	show_every::Int
	verbosity::Int
	linesearch_nan_max_iterations::Int
	linesearch_nan_factor::T
	end

Some of these are probably not needed anymore.
