Removal of security commands

Removal of security commands

The sub-commands found in the security namespace generate a very highly opinionated authentication and authorization structure in the generated web applications.

Although this type of security structure worked well for me, it might be best to leave this up to the user to decide - especially because some of its implementation was quite hacky to start with.

I will therefore be entirely removing the security namespace and its sub-commands in future releases.

Implemented in #61.

If you want to continue using authentication and authorization as they were implemented in 0.8.0, I will still try my best to maintain a separate master branch master-0.8 for versions 0.8.x which will receive the same updates as versions >= 0.9 but still maintaining authentication and authorization support.
