Just some enhancements to the new Feed page!

• You can now "like" and "un-like" an item in your feed
• Filters will now be saved whenever you apply them and re-applied every time you load the Feed page
• Usernames are now linked to the corresponding Overview page
• Fixed an annoying "bug" (not really a bug, but whatever) where the filter dropdown would disappear if you didn't click on an item exactly
