add recommended install for sierra to readme

[thejmazz]

I had a little bit of trouble setting up simbl,
seems SIMBL-0.9.9 doesn't work on sierra.
(that is, these instructions did not work for me)

In any case, I ended up getting it to work by installing mySIMBL and then restarting

figured there would be no harm if you had a line recommending mySIMBL for sierra users,
as this was my first time using SIMBL and had to dig around a bit before finding something that worked.

cheers, really liking this plugin.

aside
the "text rendering" you refer to here, do you mean how it is "bolder" ? seems to be that the way terminal.app antialiases text on retina kinda makes it look bolder (see this ). wondering if that's what you meant, or something else. personally, I like it sharper like in iTerm, but with a bit smaller font size its manageable. and worth it for ligatures

The text rendering is fixed in iTerm2 now.

Sorry for getting back so late, the project has been dead for quite a while since, as @nhooyr mentioned, iTerm2 now renders text the same way as Terminal, plus is much easier to patch around to make it behave like I want.
