Personal speech recognition (Dragonfly) command set for Google Chrome

"""
This is relevant as of 20190505. I have no plans of updating this gist. Some of
this is written in a style I wouldn't necessarily use now, but I'll let you
guess what that is.

I'm not going to bet that any of this works. I haven't updated it in months, if
not years. I know that some of the Facebook commands don't work. I use most of
the commands for Gmail regularly, but I haven't used the commands for
Google Sheets since I made the rule.

The contexts with "-~-" in them assume the use of a browser extension like
https://chrome.google.com/webstore/detail/url-in-title/ignpacbgnbnkaiooknalneoeladjnfgb
to place the URL in the title bar. I configure the extension with the string
"{title} -~- {hostname}{port}/{path} -~- {hash}". Be aware that WSR has a bug
causing it to become unresponsive if the current window title is too long. I
don't remember how many characters "too long" is, so if you use WSR…
good luck. :-)
