Script tags are reported twice in the request log when inline javascript is allowed #243

Problem is:

When inline javascript execution is blocked using CSP, this causes all external javascript to not even attempt to load.

As as consequence we can't count solely on webRequest.onBeforeLoad as the only mechanism to report external javascript files, thus we need script tags to be manually looked up in a content script.

As a consequence javascript tags are reported twice in the log when inline javascript is not blocked, from webRequest.onBeforeLoad and from contentscripthandler.js.

So contentscripthandler.js should log only if inline javascript is disabled.
