SVG icon package

[Nicolas P. Rougier]

I've made a small package that allows to create SVG icons on the 
fly from the various online icon collections. The package includes 
4 default collections (url) whose usage is (I think) compatible 
with GNU Emacs (Apache 2.0, MIT and CC 4.0). Note that the library 
doesn't include any icons, it only loads (and cache) the proper 
icon when necessary.

I also took care of fitting the icons into a 2x1 characters size 
such that they don't mess up with text alignment. My question is 
whether this can be considered for incluson into ELPA.
