Merge pull request #197 from paczian/master

added standalone version of the tree renderer
Few minor edits. First, moved buttons to after search bar so they go to second line if renderer is too narrow to fit everything. Second, adjusted rendered height if width is less than 366 pixels and buttons move to second row. Third, added name value to search bar input field so the value can be retrieved with CGI. Fourth, set the font for the tree nodes so outside css does not adjust it.
