* #1523 Create admin commands to handle players' 2FA data
- Create admin command to view if a player has enabled 2FA
- Create admin command to disable 2FA for a specified player
- Revert back to SHA1 as HMAC hash function so that it works with Google authenticator
- Add message to user to tell him to run /2fa confirm to add a TOTP code
Rough version.
- Introduces a limbo player state on the LimboPlayer, allowing us to add further mandatory actions between successful (password) authentication and the ability to play on the server
- Split TotpService further into GenerateTotpService and TotpAuthenticator, which wraps the GoogleAuthenticator impl
- Add missing tests for the services
- Change GenerateTotpService's interface to behave like a collection for more intuitive method behavior
- Take MAX(reg_date, login_date) as timestamp to compare against
- Remove the second "all" parameter to include entries with 0 registration date -> we expect registration date to always be set to the current date, so the parameter becomes obsolete
- Add an individual permission for each debug section (including wildcard perm)
- Create test for DebugCommand
- Refactor tests for the enum permission nodes to use the same abstract class
- Update related project files (plugin.yml, permission docs, command docs)
- Add new checkstyle checks: require Javadoc on large private methods, default in switch, declaration order & others
- Update path exclusions in CodeClimate config to match newly renamed classes (e.g. PHPBB -> PhpBB)
- Create consistency check testing that excluded paths exist as classes
- Fix some trivial violations
- Update docs to reflect new commands, configurations (account recovery, limbo handling) and messages
- Change message for the recovery code email to contain the new command
- Create task that generates commands/permissions section of plugin.yml
- Change CommandInitializer to return a List instead of Set (preserve insertion order)
- Merge CommandSyntaxHelper into CommandUtils
- /email recovery generates recovery code and resets password only if recovery code is also given
- Change data source method to return email and recovery code
- Change CommandDescription to contain a reference to ExecutableCommand class only
- Instantiate the actual ExecutableCommand objects in CommandHandler
- Separate FieldInjection from default fallback for no-Inject public no-args constructor classes
- Make CommandInitializer a normal, instantiable service
- Add various injections instead of fetching through command service
- Various migrations from legacy settings to new settings
- PlayerListener: use shouldCancelEvent() to see if chat should be canceled
- Merge permission manager listener with general server listener
- Check also in admin command that email is not already used
- Misc bug fixing (logic errors, changes lost during large merge)
- Use "email" and "setemail" as main labels for /authme subcommands
