Disables zooming by double click and context menu on marble.

Browse source 
Marble is a weird piece of Qt software, it seems that it wasn't
thought of being a library when first written. Most of its features
are not achieved by subclassing && overriding one of Qt default methods,
instead we need to eventFilter for almost everything ( which is a pain,
and a bit error prone - see our combo box delegate *puke*. )

This one's ready,  only one thing though - if we want to implement
our own context menu, we will need to use the eventFilter, and not
the contextMenuEvent.

Fixes #291

[Dirk Hohndel: this does not disable the context menu for me...]
