Frequent error of "no method matching Tk.TkWidget(::String, ::String)" when using Images.jl

[cvcore]

Description

This problem happens to be every time I use Images.jl inside juno.

Reproduction Guide

Inside Atom, with uber-juno installed, type:
cmd-j cmd-o to open console, then:

using Images, ImageView, TestImages to import related package(you may need to install them first) and
img=testimage("mandrill") to request the test image. After this command atom will throw out an error:

Error displaying Array{ColorTypes.RGB{FixedPointNumbers.Normed{UInt8,8}},2}: MethodError: no method matching Tk.TkWidget(::String, ::String)

Currently you can inspect the content of an image by display(MIME("text/plain"), img) but that's far too unfriendly.

I'm pretty sure this happens because of JuliaGraphics/Tk.jl#117. Not sure what the best way forward is though.

@pfitzseb So is there anything can be done on juno's side? If I try it in jupyter everything seemed normal.

[pfitzseb]

We could use Text{typeof(x)}(x) instead of Text(x) I think, but that's pretty ugly. Jupyter apparently doesn't use Base.Text, so it's not an issue for their setup. I'll also look into alternatives though.

[pfitzseb]

Changing this line to import Base: ==, bind, getindex, isequal, parent, setindex!, show, string solves the immediate problem, btw. Not sure what this might break though.

@pfitzseb thanks for the quick workaround. I will test it for a while and get back if anything happens.

For reference: JuliaGraphics/Tk.jl#138

So far so good.
