- use a non-daemonized python thread
- shut the server down on exit, including from profile manager
- use a timeout on requests, or the connection that webengine holds open
will block the thread and prevent it from exiting when anki closes
- js code that was previously bundled in .py files is now in the
web folder
- add helpers to create links to bundled files, and update
stdHtml() to accept a list of javascript files to include
instead of text
- render MathJax in card layout and preview screens - these should be
updated in the future to update the document dynamically like the
reviewer does
- start media server earlier so it can be used to serve content for
the toolbar, etc
- work around a bug in WebEngine on Windows that could cause the
media server to hang
