Remove unused contentsBox connection from Read Me.

2014-12-13 11:35:03.019 Pester[46856:13484177] Failed to connect (contentsBox) outlet from (NJRReadMeController) to (NSBox): missing setter or instance variable
Merge with latest BDAlias for 64-bit compatibility.

Still full of deprecated stuff, but it’s one step closer.
Fix some integral data types and format strings for 64-bit.
#ifdef out code so Pester becomes barely functional in 64-bit.

Things that are explicitly disabled:

- using the QuickTime audio context to direct media audio to a particular device
- NJRFSObjectSelector removing mark column from menu (currently unused anyway, as script actions aren’t enabled)
- using Notification Manager to control dock bouncing

Pester does launch and minimally work on 64-bit now, but there are still huge numbers of deprecations and warnings to go through; also, Sparkle isn’t currently building in 64-bit (though that’s trivial to change).
Replace use of deprecated text measurement method.
Migrate from deprecated OCUnit to XCTest.
Fix some more integral data types and format strings for 64-bit.
