[development] override theme of another module

[Roman Chyla]

Thank you Nevets for your reply,
I know it would be possible to use templating and in the module the
theme() calls are used, nevertheless,

(1) the ejournal module can operate several "publications" and each of
them may require its own specific themeing - ie. one module, one site,
several journals with different look
(2) imo, it is not so friendly
