Merge pull request #29 from Crabgrass/bugfix/various

Broken form in sending notifications and other places
let's make the post reply form actually visible.
added 'buttons' method to Formy::SimpleForm. I don't know where it went - wasn't it a sub_element at some point??? I can't find it.
simplified Formy::Element#method_missing (in 'def x(*a) end' 'a' will never eval to false, also passing '&nil' is equal to passing no block variable at all)
fixed tag list in pages sidebar
fixed tag cloud in "Tag..." search filter for pages
make warning about deprecated string-based interpolation go away
don't HTML escape query params in search filter buttons
removed Formy::Element#method_missing - which didn't do much but hide uncaught exceptions in HTML comments
fixed typo revealed by removing method_missing
