P0-A11: Part 967: Server, Improvements

I have made improvements to the character creation system.

It is now possible for users to create their own character from the client (Previously an entry in the database needed to be made by an admin first).

Secondly, each new character that is created will be placed at a random location in a random system. Previously, all new players would be created in the same place. This new approach is more realistic.
