[web2py] How about LOAD(..., loading='loading...')?

[Iceberg]

Hi Massimo,

So far the LOAD(...) hardcode the loading message as "loading...". I
suggest to make it customizable. Such as:

    def LOAD(..., loading='loading...'):
        blah blah

This way, developer has a chance to do i18n by:
    LOAD(..., loading='say_loading_in_chinese')
or a fancy one:
    LOAD(..., loading=IMG(_src='..../loading_animation.gif'))

By the way, LOAD(...) has seemingly no document in web2py.com/book
yet.
