Install web development tools to Mavericks (OS X 10.9)

Strongly opinionated set of guides to quickly setup OS X Mavericks for web development. By default OS X hides stuff that normal people don't need to see. These settings are better defaults for developers.

I don't want: any sounds, annoying confirmation dialogs, hidden extensions, superflous animations, unnecessary things running like Dashboard, Notification center or Dock(Alfred/spotlight works better for me).

These are my opinions. Read this document through and pick up the good parts to your preferences.
