Update checker Git dependency?

[aaronaxvig]

As I wrote about some here, it seems that the update checker has a Git dependency. (I haven’t looked at the code that carefully, please forgive me if that assumption is wrong.)

Normally this would not be a problem if you follow the install directions directly as they specify running a git clone command so naturally you must have Git. But I did it using the GitHub Desktop option, and someone could certainly use the Download As ZIP option from GitHub.com too.

I don’t really care too much since they program still runs and I have figured out how to get rid of the exception that it causes. But I thought I might pose two questions:

1. Should there be a note in the manual install instructions that Git on your path is a requirement?
2. Should there be a Git dependency in the first place for checking for updates?
