Brand new board

It is a complete rewrite of the board.
The board is now able to group tasks by the owner
The board is now able to layout the tasks onto on one another, this
makes them take less space, and furthmore, if there are more than 5
tasks in a group they will lay out in two columns.
there is a ton of more changes...
the new board should be default
added search functionality
bug on some installations where all the php was never evaluated

this seems to do the trick...
fixed the history logging, and some minor bugs with presenting error messages
