Response ─┬─> TextResponse ─> TextResponseImpl
└─> TemplateResponse ─> TemplateResponseImpl
* split up giant files, one per response path
* caching becomes a trait, implemented where necessary

and store in session for display at a later time

* the great unfuckening of user and displayName
* `login` is purely used as login with AUTH_MODE_SELF
* `email` may now also be used to log in (if the system knows it)
* `username` is purely used for display around the site, and lookups from web context
* both must exist because of external logins
a) that may be not unique
b) you may not want to share with the rest of the world
* todo: implement rename ( because of b) )
* update spell attribute descriptions primary from TC, secondary from Wowdev Wiki (not guaranteed to be correct for 335)

* provide empty values for non-default db fields when initializing external accounts
* removed browser check for username maxlength as it depends on auth method
* detatch from User and Util and move to its own enum class
* added definitions for all locales the 12340 client could in theory have
* this is incompatble with the Intl extension
