Fix injectScripts

[wvengen]

It seems sw.js has changed, and the sed command to insert inject.js doesn't work anymore. Fix this.

Is it fixed by now?
I tried to install it by using the dockerfile but get an error regarding inject.js file.
I am still new to docker. Sorry in advance for dumb-dumb questions.

Terminal output:

sudo docker build --tag 'replaywebpage' .

As described in the readme I added the version number in the docker file by substituting "VERSION".

Was fixed by da730f9 (iirc), but it could be that it needs to be updated again. As I'm not actively using this at the moment, I cannot confirm this currently. PRs are welcome, though.
