Bug #674272 - Contacts preview differs with mailer running and not

This splits the giant EMailRequest to individual EFileRequest, EStockRequest, EHTTPRequest and EMailRequest,
making the first two available globally from e-utils, the othe two are loaded only with mailer,
since no other component uses them.
