[optimization request]Try to provide local resources for all buttons

[d-packs]

There is an insane amount of javascript files and additional requests for each social network when using their official buttons.
Here is a pingdom result for a brand new installed blog just for this testcase with only this plugin enabled:

And here is one with your plugin disabled an a competing plugin called Simple Social Buttons enabled:

What the other plugin does is use local simple resources and not allowing all the analytics files to be loaded from each social network.

That plugin is really light. Could this be done in this plugin also?

Oh, It seems to be x2 faster than my plugin.
Thanks for details. I'll try it later.
