#10 Split configuration up for Search and Indexer Search

[mwelburn]

Right now, the <attribute> node in config-details.xml has an isSearchForm attribute that determines whether it shows up on the search page. Unfortunately, this drives two separate screens: the actual search page, as well as the indexer search when looking for folders to index documents into. (As such, I "think" this only affects folders). It would be nice if there were two separate attributes, in case someone had a desire to use different attributes for the two separate pages.
