Many changes:
-Become more of a proper Fog Service.
-Drop most of the Collection/Model customizations.
-Add a hook for services to do something after #new with the instance
-Move to the ToHashDocument parser ... so no more having to actually
make parsers.
-Fog::Vcloud::Extension is kind of like Fog::Service, but for writing
extension modules to Fog::Vcloud.
-Fix up existing specs/mocks (they're not complete atm, but the existing
ones are up to date).
-Fog::Vcloud::Terremark::Ecloud gets almost all extensions implemented
(almost).
-Fog::Vcloud::Terremark::Ecloud bumped to working with the current TMRK
API release.
-Factor out some TMRK/ecloud specifc mock data into the ecloud module.
-Probably forgetting something.
