Rationalise base and geerdes classes, constructors and methods.

Ignore-this: d9d4d88566a6d110844d91d4c70513cd

Towards a more standardised interface. Some of these changes (generalised
constructors and reader functions) are necessary for amuse-database-admin
functionality and some other CHARM-like things.
