SampleApp cleanup.

SampleApp fixes.

On Android, delete gWindow before calling application_term, avoiding a crash
each time the app closes.  Also make sure the screen is redrawn when resuming.

On Linux, delete gWindow to avoid memory leak.

In general, allow moving from sample 0 to the last sample.

If we're going to export postInvalDelay(), lets scope the name better:

1. SampleWindow::PostInvalDelay() -- static public method
2. SampleWindowPostInvalDelay() -- big name to its clear what it means
3. other

How about SampleWindow::postInvalDelay() - public instance method:
{
    SkEvent* evt = new SkEvent(view_inval_msg);
    evt->post(this->getSinkID(), 1);
}

Sure, if the caller has access to the actual instance, this is even better.
