Airfoils search

Actually, I think of two features:

• One simple and essential: being able to search and select an airfoil in geometry from the list (not just a dropdown that I can't enter text in), because names sometimes differ from airfoiltools and it's simply long to crawl the list and pinpoint the right one.
• One more advanced: providing Cl/Cd for each (if you have it, or the most interesting?) of your airfoils and Re, and being able to sort them, like on airfoiltools: Heliciel/Mecaflux also has a searchable database that stores Xfoil (PACC) results for numerous profiles (I told you I'm using a lot of softwares).

Searchable airfoil drop-down menus are implemented. Available since 4.24. The second item is open and work for future releases.

First part is solved. Second moved to separate issue #12
