OK, this commit try to fix the mess we have done with icon names in elm.
I just added standard names to icons yet existing in the elm theme, the
old name are, of course, preserved. But I marked them as -deprecated-.
Also added a new test: Icon Standard. It show all the icon that have standard
fdo names. This can be really usefull for user that need to choose icons to use.
I put some guidelines comment in the icons.edc files, I hope people will follow
the rules from now on... or will recive my personal spanking :D
I will work on those icons more in the next days: will add the new names to
elm docs, will try to match better fdo icon names, and maybe also add some
new icons...
Suggestions are always welcome.
@feature (maybe)
