Add a new action for interactive git-clean: filter by pattern. When
the user chooses this action, user can input space-separated
patterns (the same syntax as gitignore), and each clean candidate
that matches with one of the patterns will be excluded from cleaning.
When the user feels it's OK, presses ENTER and back to the confirmation
dialog.
