Why is limit_to not exposed for TIKZ

[H-M-H]

I tend to use \includegraphics for TIKZ pictures a lot but in this case I need them without preamble but with the .tikz file ending. Is there a reason why limit_to is set to :all only?

TikzPictures.jl/src/TikzPictures.jl

Lines 101 to 105 in 5bca9c2

	mutable struct TIKZ <: SaveType
	filename::AbstractString
	limit_to::Symbol
	TIKZ(filename::AbstractString) = new(removeExtension(filename, ".tikz"), :all)
	end

I can workaround this by changing limit_to after creating a TIKZ object and this seems to work just fine.

Feel free to file a PR where we can pass in an optional argument.

Alright, have a look at #70 then.
