[gnoduino: 21/237] Removing F("string") syntax for now.

[Lucian Langa <lucilanga src gnome org>]

commit 6c7c74e91e13ae6b9407f73f6a5d840e7d8b2370

    Removing F("string") syntax for now.
    
    We should probably add something like this back in later, but I want to do one thing at a time.  This removes the __FlashStringHelper class as well.
