Automatically convert participants to array
Fixed Group functions. Now add/end group, add/remove participants, groupInfo and getGroups all work reliably.
Wait for Response for sendClearDirty
Removed old sendBroacastPlace (replaced with sendBroadcastLocation)

Renamed sendLocation to sendMessageLocation for API consistency.
Fixed sendGetClientConfig() from reporting an error. But still no useful data returned.

Undo sendClearDirty change.
GetPrivacyBlockedList waits for response from server.
