[feature request] Workers support

[CezaryDanielNowak]

When running blurjs, there is noticeable lag. Using Web Worker to transform image would fix the lag :)

Yeah! You're right. Do you or someone have any clue on how to do that? I'm trying to make it possible, but the entire plugin is done in jQuery, and worker's need to be in native JavaScript.

If there is workers implementation I'd definitely use it. Lag is too heavy

[CezaryDanielNowak]

For now lag is caused also by events handled in wrong way. In my fork there is a lot of performance fixes:

I'll look into your fork, thanks @korpirkor !

The blur method you use is significantly faster, but also uglier. I'll study both to see which one suits me better, thanks!

You can still use StackBlur instead of StackBoxBlur, just revert this commit CezaryDanielNowak@58878ab . I could make switch for blur algo but it would increase file size

I've finally done it by using Web workers.
