Compiling F-script with XCode 4.3 and OS 10.7

[Jonathan Mitchell]

Building F-script on OS X 10.7 with Xcode 4.3 can be lethargic.

The culprit is:

@interface FSObjectBrowserView (FSObjectBrowserViewObjectInfo)

- (void)fillMatrix:(NSMatrix *)m withObject:(id)object;

@end

This function is massive (3000 lines +) and on my machine takes 10-15 Minutes and uses 4GB of memory.
The build performance on Xcode 4.2 is worse than on 4.1 and Xcode 3.

To help alleviate the problem I have refactored FSObjectBrowserViewObjectInfo.m to include a helper object that breaks the function down into smaller blocks. This allows the file to build in about 20secs and use about 250MB of memory.
