Add missing events and methods to cast proxy

The emsg, loading, and unloading events were present in v2.0.0.
The drmInfo, isInProgress, and keySystem method were also present in
v2.0.0.  The getPlayheadTimeAsDate method was introduced in v2.0.1.

None of these were proxied to the cast device until now.  All v2.0.x
events and methods are now being proxied.
