added class ".input-search-small" to selector "#keyword" in css

this happened as a result of me changing the height of the keyword search
input field in the blue sidebar, setting the id "keyword" to heigh 44px
because the seach field on the home page also has the id "keyword",
the rule applied to both
this is a result of sloppy css.  an id should only apply to a unique element
on a page.  my solution works for now, but we might want to think about cleaning
up this css and looking for other instances of mishandled class vs id selectors
