Add sanitizers to register.json

[lcharette]

As discussed on chat, "sanitizers" : { "raw" : {}} needs to be added to register.json scheme to match user-create.json scheme. Will fix weird behavior when a ' is used in user_name.

(I can't create pull request right now as I already have one open in the master branch of my fork)

Yes, sounds good as a hotfix. For others finding this issue, please note that sanitizers as a whole are deprecated in Fortress v2. Instead, we will support optional data transformations.

This also covers login.json. As it stands, register.json and login.json match eachother, so logins are possible. Users created by the admin control panel (user-create.json), however, will not be able to log in if they have HTML entities in their username. Any fix should include an upgrade of previous usernames to the proper format.

As discussed in chat, there are two options:

• Upgrade users as they log in
• Upgrade all users if their database version is less than the version this fix is added in

Any update on fixing this in 0.3.1?

If someone runs into this problem and wants to do a PR for a fix, feel free to re-open this issue. Otherwise, I suggest we concentrate our efforts on V4.
