added 'channels', 'no-sidebar' and 'no-external-references' options

[lsmith77]

still very much a python n00b but trying my best :)

fixes https://github.com/hfaran/slack-export-viewer/issues/90

these options allow me to generate logs like the following: https://github.com/symfony/diversity/commit/df8e324e757d1446ab6f242d8dbba85d7dfe3163

you can see the real life html here: https://symfony.github.io/diversity/diversity-meetings-2019-01-03.html

thx for the feedback!

[lsmith77]

@hfaran anything else to fix?

[hfaran]

@lsmith77 one final thing before I merge this - can you please add a couple screenshots of the UI to demonstrate an example without these options turned on and one with the options? Thanks!

[lsmith77]

here is link to a rendered output https://symfony.github.io/diversity/diversity-meetings-2019-01-03.html

or do you prefer a screenshot?

I think this broke the "single-file export" CLI command added in https://github.com/hfaran/slack-export-viewer/pull/79

@rmacklin I just fixed this and published 0.9.5. Please let me know if that works.

Thanks, it works in 0.9.5 👍
