Edits for standalone.tree.js

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.

Tobi, if you'll allow these edits, I can just make Retina a submodule of Metazen rather than maintaining a separate copy of 'standalone.tree.js'.
