fixed mastodon labelling and issue with numerical entities (with form &#NN;) being treated as hashtags and messed up

committing the current state of WEnotesClient.js so I can port the changes back to WEnotes.js, to, in turn, be able to recompile WEnotesClient.js with the relevant improvements. Ugh

fixed minor issues with mention formatting for wenotes clients, bumped version of wenotes-aggregator to 0.8.0

add new wenotes_wp source, with added mention content to differentiate WordPress instances, and processing of feed mentions

adding sag library as part of the project, while still a separate code base, under a separate (Apache) license

added pagage-lock.json to list of ignored files, removed sag submodule now that we've diverged from the original repo - keeping our own modified instance in the plugin

shifted uglifyjs and jquery-timeago into the package.json spec so they're installed with the other dependencies, and updated the Makefile to suit

fix mastodon posts to use data we're collecting to point properly to posts and users on other instances
