Add deprecated commands

[yannbertrand]

Display deprecated commands in a new page.

The most important work is to add a deprecated key to the defaults.yml file. Each line should at least contain a domain and a key.

Would also be great to add a new page in the websites displaying these commands.

Here is some deprecated commands:

• defaults write com.apple.dock no-glass -bool true && killall Dock
  • not working
• defaults write com.apple.dashboard mcx-disabled -bool true
  • Dashboard is dead
• defaults write com.apple.safari IncludeInternalDebugMenu -bool true
  • not working
