Icons rearrangement proposal

[Ronan Zeegers]

I've been thinking with a friend of mine (http://www.design-hero.com/) 
about the current arrangement of the icons. And I think it could be 
improved.

Here is my rearrangement proposal of the icons:

I have also removed the separator at the bottom of the Toolbar. Usually 
a separator separate from something.

btw, there is a little bug with the vertical size of the magnifying 
glass icon:
