Prevent mousemove spam

Some platforms produce frequent mousemove events whether or not the mouse has moved. This causes the UI to always be displayed since userActive_ is always `true`. By keeping track of the last mouse position and only firing if the new position is different, we can eleminate the event spam.
Fixes exception when userActive called but tech not initialized
Trigger ready callback even when no tech available so client app can display custom fallback message
- Bind hide on ended event to resolve issue #1028.
- Remove duplicate seeked event line.
Added comment to triggerReady call
Enough to check for this.tech != null
