[mono-android] Binding services

[Jon Dick]

I'd add that I've mostly opted to find .net ways around using service
bindings.. It won't be the best in all cases, but a simple static event
living in the service class that passes a reference to itself to the event
handler can go a long way :)

Then you make your Activity register and unregister for the event on its
resume and pause overrides... Simple, and I don't think the performance or
memory implications are terrible.
