* Adding visual captchas for register and login.
* Adding audio wav file for Captcha using espeak.
* Lots of captcha fixes.
- Removed login captchas.
- Added settings to disable captchas, and change difficulty.
- Captchas can only be checked / used once, front end gives a new one on
failure.
- Added front end button for regenerating captcha.
- Added a disabled / pause button audio playing.
* Some more fixes.
* Remove extra jwt claims (for user settings)
- The JWT token only contains the issuer, and your user id now.
- Now only a page refresh is necessary to pick up your settings on all
clients, including theme, language, etc.
- GetSiteResponse now gives you your user and settings if logged in.
- Fixes#773
* Remove extra comment line, I tested nsfw
* Adding a todo to add a User_::readSafe()
- This adds a form_id to CreateComment, EditComment, and CommentResponse
- This is so any front end clients can add a randomly generated string,
and know which comment they submitted, is the one they're getting
back.
- This gets rid of all the weird complicated logic in handleFinished(),
and should stop the comment forms getting cleared once and for all.
