(AHK) Updates on code snippets
(README) For the hotstrings, added the optional script to use the clipboard....this is much more efficient on some platforms (eg sublimetext)

However, the drawback is that it'll erase the clipboard item that existed prior to the hotstrings...
TMP=clipboard approach in AHK syntax is more confusing than I thought...may try to fix this in the future.
