Set architecture to 32/64-bit universal

One of the last commits seems to have accidentally removed x86_64 as a target architecture.

Also restored deployment target to 10.5 (from 10.4).
Server-side support for apps with spaces in name

The server-side submit script now supports apps with spaces in their name by removing the spaces. For example, the submission folder for "MainMenu Pro" becomes /path/to/feedback/MainMenuPro.
Replaced Gestalt() (deprecated in 10.8) with sysctl() for CPU frequency and physical RAM.
