Use git tag for versions

[light-and-ray]

Hello, in every your commits you edit version_flag = "v0.7.0-b6" line. It looks like a crutch. Maybe you should use git tag instead, like A1111 does? https://github.com/AUTOMATIC1111/stable-diffusion-webui/blob/master/modules/launch_utils.py#L75 It increases automatically for dev branch, and manually for master branch

And also I think it's not really necessary to write version in readme file

Hi, I'm used to this versioning scheme for projects where mostly one developer participates
The "version_flag" variable is not a crutch, it is used to display the version in the console and in the WebUI
Yes, of course it can be automated (not a big deal), but when there are not a large number of daily commits - manual versioning is not a pain, so I'm ok with this
But anyway thanks you mentioned this point
Perhaps I'll automate this in future if there's much more active development with a lot of devs involved
