New icons for "express searches"

Some people said that they did not understood the meaning of the buttons, in the main screen.

The issue was mainly with the express search.

So I tried to do the job by myself: 

If you are an artist like I am... (!^_^) you then understand that : 

• The first button is dedicated to the express bikes search (I want bikes nearby !)
• The second button is dedicated to the express slots search (I want slots nearby !).. and not to prevent riders from hitting a wall, a car or any orange object that can be represented by the orange part (!^_^)
