Trying to get building on modern Xcode / OS X.

- Update to recommended project settings
- Set target to latest OS X
Add .gitignore, trying to get compile working.
Delete from index these files that should be ignored.
Still trying to get to build. Removing stuff that references 10.4.
Still working on compiling.
Getting closer, maybe.
Here I've started to change behavior trying to get things compiling.

Running into this issue: http://stackoverflow.com/questions/18449176/objective-c-format-string-is-not-a-string-literal-potentially-insecure-warn
[Edit: This is still not "working", but you can compile and install it!"]
Updating paths.
Fixing the thing I messed up. A bit. Fixing is a bit.
Fix one more.
