Simple and effective target that builds ALL fixins.
Added script phase to add xcode5 "compatibility" to all targets.

Also squelched some "validate" warnings in xcode.

Xcode5 compatibiliy / Info.plist postprocessor build script. Workspace tidy.

Simplified workspace a bit, working build script to enable/disable
troublesome build targets and postprocess Info.plists to add
DVTPlugInCompatibilityUUIDs, etc via `defaults write`.

Refactored Hide Distractions.

Fixes #20.  Seems faster, too.  Tested and workng on xcode4 and 5.
Fix up build architecture settings.

(As best I can tell: plugins need to build for both 32- and 64-bit
architectures, except for CustomizeWarningErrorHighlights, which
fails to link in 32-bit mode.)
