mislav/will_paginate + (4) -

    - Added parens around method definitions (huge pet peeve of mine, sorry)
    Slight finder rewrite (yeah, again ^^). PaginatedCollection is now Collection and no longer only a proxy, but a real Array subclass. That cleans things up quite a bit! I'm clearing the way for more view helpers. Also, SEPARATOR constant is added to act as a default separator for page numbers. Initially it is a single space, which kinda reverts [207] (sorry PJ!).
