[widgets] Default icon proposal

I'm wondering if we should have a default icon file name for the
widget spec? (that way, an author can omit the <icon> when they just
want to use the default). The default icon name would be "icon.png"
(case insensitive, must be png) and it wouold be included at the mount
point of a widget package ("/icon.png"). Even if the default icon is
included, authors are still able to declare additional icons in the
configuration document. Default icons are as the one I am proposing
are currently supported by Dashboard and Nokia's WebRuntime.

Anyone in support of this?

Kind regards,
Marcos
