Switched to a `make` based build system, bumped version to 9.3RC1.
The build scripts for PostgreSQL and dependencies have become an unmaintainable mess. Everything was stored inside the project file, making diffs totally unreadable. Now building is performed using a makefile. The `make` based workflow has been added as an external target to the Xcode project. As a result, builds should be faster, because dependencies aren't rebuilt as often any more.
Furthermore, this commit also includes an updated dylib linking script, which should be faster.
- updating .gitignore so i can add the new makefile
- added missing makefile

Fixed build for 10.7, bumped version to 9.3.0
- ensure Lion compatibility by setting MAXOSX_DEPLOYMENT_TARGET in makefile
- fixed linking issues by changing the PREFIX variable in makefile
- updated PostgreSQL version to final release 9.3.0
- updated README file (download location, build instructions, credits)
