Filtered Searching

[GodTitan13]

Add additional filtering to the search feature. A few additional options for the filter that I've come up with should be as follows:

• Listing owner
• Member count
• Online member count
• Vanity Link
• Regular Link

(These should all work as non-required options that can all be used rather then being limited.)
