@short_description: Provide a connection to the HUD service
@stability: Unstable
@include: libhud-client/connection.h
The connection is an object to maintain a connection to the default
objects on the HUD service. It provides access to the functionality
there and can be used to create queries.
Most users should not bother with a connection, it will be created
by the #HudClientQuery if one is not provided. Most usage is for
testing and using custom HUD services.
