Build failure.

[blenko]

Build of AppKiDo fails on Xcode 4.6.3, zip file downloaded from github, 6-15-13.
AKGeneralBehaviorDoc.[hm] are referenced in the project file but absent from the files.
Further, the references are to paths outside the project.
Fixed by fetching AKOverviewDoc.[hm] from an older release, renaming to above, changing internal class declarations accordingly, adding to project files, then removing and re-adding the AKGeneralBehaviorDoc.[hm] in the project.
