Improved Xcode4/5 support, improved loader, install routine, code cle…
…anup. Moved loading routies to more reliable XCFixin model. Eliminated unneccesary and non-functional install scripts with simple compiler directives and removed unneccesary version.plist . Tidied codebase. Small edit to Readme regarding ~/.MacOSX/environment cariable used in info.plist. Changed schemes.. one for xcode4, one for xcode5 vs. debug/release.
