@ExtremeFiretop,

This PR includes the fix so that the version file is no longer replaced when doing a "script update" check.
Also, there's a fix in the GetLatestFirmwareMD5URL() function which was returning the wrong parameter for URL.

BTW, this morning, I just ran both scripts (from the master and develop branches) through the Linter tool, and they came out "clean." Last night, I was too tired by the time I had finished the code changes, so I waited until this morning to do it before submitting the PRs.
