added void osSetParcelMediaTime(double time) command to script engines.
which sets the position of the media that is playing. Time is in seconds.
Doesn't do any security checking (should be checking that the object/script is owned by the parcel owner). So could be abused, if it is then we should remove it, or add the security.
Only tested in dotnet scripting engine, but should work in XEngine too.
Another new OSSL function for returning the name of the script engine
currently running, osGetScriptEngineName, added to both DotNet and XEngine
OSSL API.
This patch proposes a new function : osOpenRemoteDataChannel(key channeID)
that allow to open an XMLRPC channel for remote_data event. The difference
is that the channelID can be customized instead of being randomly generated.
