Add --pod-sources config option to fix #650

[Jon889]

This adds the --pod-sources config option to fix #650

It's used in the same way the sources option is used during pod lib lint

So jazzy --podspec Identity.podspec --pod-sources 'https://cdn.cocoapods.org,https://example.com/private-pods.git'

btw it seems danger isn't running on the CI, though it still marks it as successful Could not set up API to Code Review site for Danger

Looks good, thanks a lot.

re. danger -- turns out we have a Circle setting that prevents it working on PRs from forks. PRs on the main repo look to be intermittently failing there too for a different reason.

[Jon889]

Ah ok, thanks for merging this :)

[robertofrontado]

Nice work 👍, Do you know when this is going to be released?

[Jon889]

Thanks! I'm not sure you'll have to ask @johnfairh

[johnfairh]

Can do a release this week I guess -- @robertofrontado have you had a chance to try out master?
