- Added GTMSignalHandler for simple signal handling (via kqueue/runloop).

- Fixed up GTMIPhoneUnitTestDelegate to be pickier about which tests it runs
- Added GTMNSString+URLArguments to GTMiPhone
- Added GTMHTTPFetcher and GTMHTTPServer to GTMiPhone
- Made sure that build would work with iPhone device attached, and that all 
  tests run directly on the phone.
- Added GTMValidatingContainers which are a set of mutable container classes 
  that allow you to have a selector on a target that is called to verify that 
  the objects being put into the container are valid. This can be controlled 
  at compile time so that you don't take the performance hit in a release build.
- Added GTMPath, which represents an existing absolute path on the file system.
  It also makes it very easy to contruct new paths in the file system as well
  as whole directory hierarchies.
- Added GTMNSString+Replace for a common replacement need.
- Added NSString+FindFolder for two commen helpers for building paths to common
  locations.
- Added GTMLargeTypeWindow for doing display windows similar to Address Book
  Large Type display for phone numbers.
