Patch: Do not load jQuery if already loaded
Hi,
I have a mashup website and can not control whether other modules pre-
load jQuery on a page. To solve this problem I encapsulated it with a
condition as shown in the diff below. This may be useful to someone,
or if you know of a better maintainable method, please let me know.
Regards
Jaco Vosloo
