Fix broken, crash-causing French translation.

The translation of IntroductionText had two occurrences of %@ in it, causing
stringWithFormat: to crash in askCrashReportDetails.  Needless to say, crashing
on application startup when trying to report a crash and preventing the
application from ever successfully launching again is less than ideal.

This could be fixed by using %1$@ for the second occurrence, but repeating the
name multiple times is not ideal, so this commit replaces it with "to the
application's developers" instead, as suggested by a native French speaker.
Show the selector name found in the current argument registers in crash reports, helpful e.g. for crashes in objc_msgSend

This is a safe implementation with only hard wiring the necessary bits for where objc_msgSend stores the receiver objects based on the CPU architecture. From: http://sealiesoftware.com/blog/archive/2008/09/22/objc_explain_So_you_crashed_in_objc_msgSend.html

In the mid/long term, PLCrashReporter will include this directly.

In addition add `bit_archNameFromImageInfo` to get the current architecture only once
Enable Skip Install again

This fixes a warning when archiving an app with the SDK included as a subproject. This has been tested with Xcode 5.0.2.

This setting was previously removed in the commit 735305cf0160e881e6bd9362ed841b53c9237802
