v2.1.7

(2.1.6 was skipped because it had a huge bug in the chrome extension, which was fixed and re-released within minutes of release)
-removed automatic retrieval and update of settings from the server; decided it was better if folks just reload to get their latest preferences
-added a "forced update" to the chrome extension — if your extension is out of date, it will not run until it has been updated. This feature has been included in this version to ensure a conflict-less update to v3 which releases in the next few months
-spelling and capitalization fixes
