#8 Adding login redirection

Some actions like shownotice or conversation weren't asking for redirection after login. Extended base Action class with redirection logic, child actions must now override redirectAfterLogin and set it to true. Directory plugin was updated as consequence.

In the commit aba9b33822

• Replace array() with []
• Revert style regressions like: aba9b33822

I believe it's ready now @diogo

Thanks! :)
