 Losing your changes is no fun.

 The way I see it, we have two options:

 1) Show an AYS when leaving the customizer by using an onbeforeunload
 handler.
 2) Store unsaved customizations in a customize_data_$stylesheet option.
 The fact that certain customize settings persist across theme changes
 (options) while others don't (theme_mods and some theme-specific options)
 could pose a problem.

 I say let's start with #1.
