Merge branch 'release/1.1.2'

* release/1.1.2: (21 commits)

Bumb version to 1.1.2.
Fix lastEvent not getting set.
compatibility shim, runtime checking example, file-level events ---------------------------------------------------------------
validate project settings, update to xcode 3.2
Fixed "missing base SDK".
Fixed a bug in the CDEventsCallback(...) code which could cause the excludedURLs to be disregarded.
Changed the lastEvent property of the CDEvents class to readonly in public and readwrite in private.
Fixed a bug in the test app which could cause an exception to be raised.
Fixed a lot of small formatting and cross reference errors in the API doc.
Fixed a dup symbols bug properly, thanks to Kirk Kerekes.
Defined MACOSX_DEPLOYMENT_TARGET to 10.5.
Added some Xcode 4 stuff to the git ignore file.
Revert "Changed two "const <type> <name>" constants to macros (they caused duplicate symbol linking errors when the header was included more than once for the same product)."
Fixed small markdown error.
Added still maintained image.
Changed two "const <type> <name>" constants to macros (they caused duplicate symbol linking errors when the header was included more than once for the same product).
Changed test application to use full CDEvents init method.
Fixed missing weak code mark in the delegate property declaration.
Changed the compiler to LLVM 1.5.
Marked CDEventsDelegate pointer as a weak pointer (for GC).

 It's an Objective-C wrapper for Mac OS X's [FSEvents C API](http://developer.apple.com/mac/library/documentation/Darwin/Reference/FSEvents_Ref/FSEvents_h/index.html). Inspired and based upon the ([MIT-licensed](http://www.opensource.org/licenses/mit-license.php)) open source project [SCEvents](http://stuconnolly.com/projects/code/) created by [Stuart Connolly](http://stuconnolly.com/).

 Requires Mac OS X 10.5, since FSEvents were introduced in 10.5, and an Intel CPU. Supports both manual memory management and garbage collection.
 
 ## What differentiates CDEvents from SCEvents then? ##
-Not all that much but a litle. First of all all classes and protocols are prefixed with `CD` instead of `SC`, I hope that won't be to hard to remember? Secondly `CDEvent` (the event data wrapper-class) is immutable in contrast to `SCEvent` which is mutable. The next difference, which were the initial reason why I decided to rewrite `SCEvents`, is that the class `SCEvents`' is a singleton something `CDEvents` isn't. I couldn't find a good reason as to why `SCEvents` had been designed that way and for my project a "normal" non-singleton class would be and is better.

 ## API documentation ##
 You can generate API documentation with the help of [Doxygen](http://www.stack.nl/~dimitri/doxygen/). In Doxygen open the file `api.doxygen`, click the `Run` tab and then the `Run doxygen` button. When it's done you should have a directory (ignored by git) in the root of the project named `api` with a sub-directory `html` in which you will find `index.html` double-click and enjoy.
