#25 Early implementation for toolbar

While I have my own toolbar plugin for FluxBB, the ModernBB toolbar will
be based on the FluxToolbar plugin. This is a very early implementation
and it will be integrated further in the near future (which is
tomorrow). After this, ModernBB 2.0-beta.3 is ready to go.
