added search_columns method to base cdbi model class, provides display_columns unless over-ridden
fix to display_line macro in factory templates (bug 22920)
fix to correct problem with LocationMatch and regex based Location directives in apache config.
+ change to view::base to only call display_columns, stringify_columns, to_cgi if model class can
+ changed template path to only look for custom, factory, etc on first/only path provided
