* NEW: somaRequest class and soma_request_[*] dynamic action hook -- works much like wp_ajax_ hooks, but without the ajax. Triggered with the 'soma_request' query_var or as simple URL query params via $_GET. Very handy for export/download functions to fire without leaving current page!
* NEW: somaFunctions::build_request_link() creates link to trigger soma_request_[*] action hook and pass along data (string or array)
* all functionality of the old somaDownload class is now incorporated in an soma_request_legacy-download action hook (though the old "download" query var remains for backwards compatibility)
