Clearing the billing log feature

I had a request to be able to clear the billing log. So, I built a feature to clear and store the log.
Also, they wanted to be able to open the log in a separate tab for easier viewing. So, there are two buttons added to the billing manager.

Do you think this would be a good addition to the code base?

nice, sure, the only way before was the setting in admin->globals->logging and manually moving the file or relying on the backup of the old log.

Ok, I’ll make a PR for this.
