Remove save and load config?

[parsiya]

This means the extension can only get a new config by using the config.json file by the jar. This will not be fun IF the extension is added to the appstore.

Pros:

• Extension will be simpler.
• Fewer items in the UI.

Cons:

• Mess with us IF the extension is added to the Burp appstore. The config file needs to be right by the jar file.
• Have to reload the extension to change the config.
