Allow to use Async call as a standard AsyncTask replacement

[GoogleCodeExporter]

Please add async method, which allow to start AjaxCallback where the result is 
not loaded from network, but is computed localy. This will be very handy for 
time consuming operations as a standard AsyncTask replacement. Simply allow to 
implement our own background work :-)

Wanted this myself couple times. Should be easy enough to add.

This is my workaround for this problem:

bmp = aq.getCachedImage(url2); 
if (bmp != null) { // if image is cached already
    (new AjaxCallbackLoadingBitmap()).callback(url2, bmp, new AjaxStatus());
} else { // if image is not cached yet
    //Log.d(TAG, "Not Cached: "+iconUrl);
    AjaxCallback<Bitmap> cbBmp = new AjaxCallbackLoadingBitmap();
    cbBmp.url(url).type(Bitmap.class).header("User-Agent", appPrefs.getUserAgent()).expire(GlobalVars.BROCHURES_EXPIRE).fileCache(true).memCache(false);
    aq.ajax(cbBmp);
}
