Customizer: Show a warning when IE <=9 or Safari is used

[XhmikosR]

Since the customizer doesn't work on IE <= 9 due to at least FileSaver.js, maybe we should show an extra warning there.

Might also want to warn on Safari; see #12567.

Sounds good, yes.

@zdroid For IE 9, conditional comments are pretty reliable.

Yes, but I don't want that. I want to just add new code to the customizer.js.

How about using the feature detection mentioned in the FileSaver.js docs? That should solve both IE9 and Safari 6
try { var isFileSaverSupported = !!new Blob(); } catch(e){}

OK, that sounds nice. ;P
