Make the descriptive comments also hotstrings.

[wyattscarpenter]

Today I stumbled upon some code I had done years ago where I had started to make the change described in the title: making the descriptive comments also hotstrings. The idea that spurred me to do this was that I can never remember the country codes for flags, so :iran flag: would be more useful to me than :flag iq:. And given that we have both, why not use both?

Anyhow, I can (eventually) make a PR for this feature if you aren't opposed and would be willing to accept it. (It would also be nice, I think, to pull in the most-recent emoji data before I make the change.)

( If this other pr of mine goes well, it may also be worth waiting and upgrading to the most recent version of AHK to avoid the 40-character hotstring limit AutoHotkey/AutoHotkey#341 )
