Enhance the home page

Things that should be added:

• tagline
• simpler description
• tell people that it is in a mega-alpha-no-guarantees stage at the moment
• single call-to-action ("Start planning!") that leads to login,

Also: make it not ugly. :)

Maybe we can also add some screenshots or even a animated gif to show off the planning interface.

We cloud do something like making a tag line and change the first word from one to the next.

BAND planning made easy! GROUP planning made easy! REPEATED planning made easy! FAMILY planning made easy!
