set up documentation CI against Julia 1.x

[johnnychen94]

The whole documentation will be largely rewritten to:

• update to Julia 1.0
• better cooperate with current Images.jl
• be CI-friendly (e.g., replace Weave and optable.jl with DemoCards.jl)

It would be impossible to review if they're all squashed into one PR, so I'll set this as the common base, and make reviewable separate PRs that points to this branch.

P.S. DemoCards doesn't have the full functionality as a jump-in replacement, so I'll need to spend some of my time debugging and enhance it.

Grid seems to be a little bit more readable. Any chance you can fix the black background?

[Evizero]

btw. I don't recall to what extend I transferred stuff here, but I do have some doc stuff for augmentor at juliaml: https://github.com/JuliaML/FileStorage/tree/master/Augmentor
In case you wondered how I created some pieces.

I know... I wasn't exactly spending much time on cleaning up my documentation "framework"

Yeah, I just tried to make a fresh build of those scripts from scratch with my own stuff. But it's doable --https://github.com/Evizero/Augmentor.jl/blob/master/docs/optable.jl gives a nice example of this already.

There're more details that need to be fixed. This is just a preview of my experiments on the layouts.

😄 that (documentation) was more than elaborative to me

This is mostly done now.

As a brief summary:

• operations gallery and tutorials are now generated by DemoCards.jl. optable.jl is rewrite with the new mosaicview and exampleweave.jl is replaced by DemoCards.jl + Literate.jl.
• deprecation and jldoctest references fixes (jldoctest only passes in Julia 1.6-dev)
• Knet.jl example is removed now, I'll add an example for Flux.jl in future PRs. (rewrite the examples and simplify README.md #67)

A lot of changes are involved here and it's pretty hard to review them line by line. I would suggest build it locally and view the generated pages.

The ISICArchive.jl package is not registered in General, so I have to hack it a bit in make.jl as a temporary solution (if I don't want to check in Manifest.toml). We should either register this package or replace it with probably TestImages or MLDatasets. I'll leave this to future work. (CRef. Evizero/ISICArchive.jl#3)

@Evizero do you want to take a look at this?

[Evizero]

I don't have a local julia installation currently. any chance you can show some screenshots of the major things?

[johnnychen94]

The biggest changes are on operations. The tutorials are built with DemoCards with a List theme.

Plots, Reel are not used in this PR; instead, I use ImageMagick to generate gifs.

Looking good. Thank you for all that hard work. Feel free to merge when you are ready

[johnnychen94]

Let me merge this and see if it gets successfully deployed to gh-pages branch

amazing!
