Make possible to install web ui without venv with --novenv flag

When passing `--novenv` flag to webui.sh it can skip venv.
Might be useful for installing in Docker since messing with venv in Docker might be a bit complicated.

Example usage:
`webui.sh --novenv`

Hope this gets approved and pushed into future versions of Web UI
