fixing format directives in advance of 64bit conversion
removed unused variable kSuccess

* implements a new strategy for creating calabash.framework using a
  Makefile + framework build script - could not create 64-bit slices
  using the existing strategy.

* the new strategy uses Debug configuration with NO symbol stripping

* Xcode 5.1 cannot find UIGetScreenImage so LPScreenshotRoute2 will be
  removed in a later commit.
