Finally fix support for OpenBSD
Create virtual key up events for all pressed keys when the display loses focus.

This is a workaround for missed key events and incorrect key state reporting. This is actually a cleaner solution to the previous workaround on Windows and works nicely on Linux too.
Refactored the OS X script for better readability and to enable builds on newer versions.

Issues resolved:

- Added support for the 10.8 (Mountain Lion) and 10.9 (Mavericks) SDKs.
- Dropped universal builds on 10.8 or higher, x86 is not supported anymore.
- Use clang instead of gcc on 10.8 or higher. Fixes a system header compilation error on 10.9.
- Fixed issue with the libjawt path on certain JDKs.
