android-formidable-validation

Fixed linkage in README;

Fixed erroneous example image links; Added Android Assets Viewer link (because I can, hehe);

Added some example screenshots and updated README to look all purdy like;

Lots of improvements: added fraework for overriding TextView subclasses that already have setError (i.e. betterSetError); ValidationManager now calls betterSetError() if possible, else setError() if possible; Added missing drawables for resource folder variants; Added green-ified versions of error popup and error indicator graphics to differentiate between SetErrorAble Views that have betterSetError and native Views that have setError; some cleanup; some bugfixes;
