Slightly tweaked the filtering algorithm to allow reposts if the username of the user reposting the track appears in the track title. This addresses the following scenario: you follow A; B posts a track which A contributed to; A reposts it. This is commonly seen with labels, collaborations, and remixes.

Fixed an unintended interaction with reposted tracks from people you follow. Such tracks will no longer be blocked (given that you are following the original artist, you probably want to see their songs).

For technical users, this also switches the blocking method from network request interception to monkey patching XMLHttpRequest via content script. There should be no user impact from this change.
