It was changed the vertex influence visualization for Sculpt and Tweak/magnet as well the code related to it was reorganized and standardized. It was also fixed a bug in sculpt module.

NOTES:
- the Magnet influence in Tweak/Sculpt mode is now shown by using edges highlighting; [Micheus]
- it was added an option to Preferences dialog for Sculpt and Tweak that makes possible to enable/disable the visualization resource; (suggested by Fonte Boa) [Micheus]
- if Work mode is off (unchecked in the View menu) no visual effect is drawn; [Micheus]
- it was changed the way to adjust the Magnet radius in Sculpt mode in order to be consistent with the same operation in Tweak; (suggested by oort) [Micheus]
- fixed a issue in Sculpt module related to the use of shift key for activate smooth functionality while using any other sculpt mode. [Micheus]

Mac file dialog plug-in: Don't try to use 'gcc-4.0'

There is no longer any gcc-4.0.
Mac: Force 32-bit build

The latest version of Xcode defaults to a 64 bit build.
Update Wings3d.xodeproj for Xcode 4.5.2
MyController.m: Eliminate warnings

The first argument for NSLog() should be a format string, not an
arbitrary string.

The Gestalt() function is deprecated starting in OS X 10.8.
Since the only purpose of the call was to avoid running on too old
versions of OS X, we can simply remove the call since the deployment
version set in the binary will server the same purpose.
