Sunway: Fixed issue, Player continues walking if mode changed during walk

[sunwaylive]

The player stops walking immediately on pressing the right mouse button, and I think it's more user-friendly compared to make it a feature for usage in long walks.

Ok, I've capitalized the first letter in your name in the commit to make that clearer. I cherry picked your commit rather than merge it (mainly to make the history cleaner), so you need to rebase on Ember master.

Ok.
