Adds first release of DOI For Translation Plugin to the Plugin Gallery

[YvesLepidus]

This plugin allows to create a copy of a submission, where this new submission represents a translation of the original in a certain language. In addition, it will send Crossref the hasTranslation/isTranslationOf relationship linking the DOI of the original language with the DOI of the submission that is a translation.

Thanks, passed along to @ewhanson for review!

Looks good to me! 👍 I did see one minor I'll include below, but I don't think it should be blocking to the plugin's inclusion in the plugin gallery.

Adding the plugin-specific CSS happens every time the plugin is registered, regardless of whether it's enabled or not. It should probably be included in the if statement above where the hooks are registered, but I don't think this will cause any problems in practice as the amount of CSS added is so small.

Thanks, @ewhanson !
We'll fix it to load the CSS only when the plugin is active. Even though it's not blocking, we can fix it tomorrow.

Thanks for the review, @ewhanson !
We've changed the plugin so that the CSS is only loaded when the plugin is enabled.

Perfect, thanks @YvesLepidus! @asmecher, this is good to go from my end.

Merged -- thanks, @YvesLepidus and @ewhanson!
