project cleanup and relocation of install directories

[Christopher Lloyd]

Hi,

I've gone through and cleaned up the projects a fair bit. The most significant ramification is that the final frameworks are now in <working copy directory>/system/<target-triple> instead of /Developer/Cocotron/1.0/. This allows one to have multiple clones on the same system without install directory interference.

You'll need to reconfigure your Framework/header include directories to point to your working copy.

- relocated install directories to relative working copy

- relocated most of the third party library support to relative working copy (e.g. hunspell, agg, etc)

- moved most platform build settings to xcconfig's

- removed a lot of pointless build phases

- removed most use of target build rules for the compiler, no longer needed with Xcode 4

If you have a clone, please consider merging with the mainline, this will allow me to pull changes more easily.

The Darwin x86/i386 targets now build with clang, so if you want to work on non-AppKit dependencies, it's now easier to do this locally.

If you have any problems, please let me know!

Thanks,

Chris
