Support for multiple boards

[ajax333221]

It is currently not possible to display more than one board at a time (even though we can have multiple virtual boards) because the limitation of not being allowed to have multiple DOM elements sharing the same id.

It would be good not to force the components to have those very specific mandatory id-attributes and rewrite them in a way that we can work with multiple boards visually and no just internally.

The way the auto binding of components work makes this change very hard to implement, a big rewrite needs to take place for this to work.
