Geoffrey McRae 84b2917706 [client] app: new options to reduce CPU usage
This patch increases the default cursor and frame polling interval from
1us to 1000us which for most use cases should be more then fast enough.

It also adds two new configuration options to adjust these should it be
required:

  * app:cursorPollInterval
  * app:framePollInterval
