Ability to make suggest preview and inline completions case insensitive

[svipas]

I really like "editor.suggest.preview": true setting and inline suggestions (editor.quickSuggestions), but what I miss is ability to make it case insensitive, so I don't need to type exact word to show, what I meant is instead of parsePhone I could type parsephone and it still shows, because the final word is parsePhoneNumber.

When I type this:

Still show suggest preview for the rest of characters. Same applies for editor.quickSuggestions -> inline.

This would play really nice when you use only inline suggestions (editor.quickSuggestions), because you don't see suggest widget and if you miss that upper case it hides preview.
