fixed warnings about selector ambiguity and unused parms
Put FRLocalizedString macro in its own file.

Removed the FRLocalizedString macro from FeedbackReporter.pch and placed it in a new file named FRLocalizedString.h. Added the new file to the Xcode project.  #included the file where needed.  This makes it easier to embed the feedbackreporter files into your own project instead of building feedbackreporter as a framework.
Fix -Wformat warning by avoiding unsafe use of stringWithFormat:

Use stringByReplacingOccurrencesOfString:withString: instead of stringWithFormat: where the first param is not a literal string.
