Layout/Sidebar: add support of Gravatar to fetch main picture

[Horgix]

Description

It is currently only possible to directly reference an image for the main avatar/picture in the sidebar. This Pull Requests adds support for getting this image from Gravatar by only specifying the email address to look for in the hugo configuration (config.{toml.yaml,json}).

If the gravatar field of the [params.intro.pic] section is set, it will take precedence over the existing src field. This hence doesn't change anything for current users just updating the theme. The concerned gravatar field has been added to the example site configuration and defaults to an empty string, effectively disabling it.

Any news on this? Can I help with something? :slightly_smiling_face:

@Horgix Sorry I have been super busy and am actually working on a rebase of most of the theme.

[Horgix]

@pacollins : no worries :slightly_smiling_face: Will this have a chance to be merged before the rebase of the theme? If not, should I close it and just maintain my own fork? Thanks!

[Horgix]

I guess that after 5 years there isn't much hope to see this merged, and am therefore closing the PR.

Good luck with the future of the project and its maintenance! :slightly_smiling_face:
