Disallow usernames that contain certain words and RegExp (#2200)

* Add `disallowedwords` setting and perform check

Check if any of the words in `disallowedwords` are contained in the username. If
so, return false like other checks.

NOTE: Needs testing for advanced bugs.

* Remove "administrator" from `disallowedwords`

"administrator" contains "admin" anyway, so it is not needed.

* Add error message if username contains a disallowed word

* Add `disallowedregexp` setting and perform check

Check if each expression in `disallowedregexp` exactly matches the username. If
so, return false.

TODO: Add specific error to dialog in `window_main.cpp`.

* Add error message for username matching RegExp

* Fix indentation

* Compile `disallowedregexp` into a QList upon initialization

Reduces system load with each registration request.

* Clean up `isUsernameValid` function

* Fix indentation

* Add backwards compatibility to client

Client can accept either 7 or 9 rules to maintain compatibility with older
versions of server.

* Add examples and warnings to `servatrice.ini`
