Cocoa Port: Begin work on cleaning up and refactoring the cheat system. Also add some quality-of-life improvements to the GUI while I'm at it.

- Add new ClientCheatItem C++ class to handle cheat items, greatly reducing dependence on Objective-C code.
- Remove a bunch of methods from CocoaDSCheatItem and CocoaDSCheatManager that were never used and are no longer planned to ever be used in the new code refactor.
- The Cheat Manager window may now be resized.
- The Action Replay code editor now uses Monaco 13 font instead of the system default font.
- The command for "Enable/Disable Cheats" has been renamed to "Enable/Disable Cheat System" to help clarify that the command affects the entire cheat system as a whole, as opposed to enabling/disabling individual cheat items.
