Suggestion: move .png/large data to wiki repo

[ocornut]

Minor trick/suggestion: because png adds up in the git repo size.
The wiki that github offers is a separate git repo (ImGuiColorTextEdit.wiki.git instead of ImGuiColorTextEdit.git)

What I do for imgui is I upload any images to the wiki repo and link to them from the readme instead, so the main repository doesn't grow with extra data.

@ocornut Maybe git LFS can do the trick too (but keeping the image ref into the same repo) ?

I believe there's no use for the end-user to even have this image locally, they want the code?

Done.
