Live folders

Heya,

I played a bit with Tomdroid recently and added the support for live
folders. This is a cupcake feature and thus bumps the requirements to the
version 1.5 of Android. I don't really think it is useful at the moment but
it may be in the future so I'm attaching the bzr merge directive to this
mail.

There is one thing I'm not really sure about the code: the NoteCollection
and NoteProvider classes. The first one seems to parse the xml notes and
puts them in a sqlite database while the second one is the main point to
add, remove and modify notes and deals only with the sqlite database. Did I
understand things correctly?
