Merge branch 'app'.

The app objects both makes the whole program sort of behave like one
class in some object oriented languages, with an implicitly (actually
hiddenly explicitly) passed 'app' argument to all methods. Multiple
concurrent apps should be supported, but is of now untested.

The app is also configured to lazily bind all its fields, which means
that almost all loading is now lazy!
