Limit WARC header/content capture to current tab only
Currently, asynchronous requests from other tabs pollute the WARC if they occur during the WARC creation process.
This might be fixed by limiting the capture to the current tab in the response and request capture filters but requires a bit more testing, which should be easy enough by keeping some other site that extensively uses Ajax open in another tab.
For testing, throw this page ( http://warcreate.com/tests/bug7.html ) up in a tab, new tab, enable WARCreate with a simple HTML page, and note the noise included in the WARC.
Is this the right functionality or should it be "all of the tabs the user visited with WARCreate enabled."
