Fix Earned Achievements widget handling for achievements with spaces and special characters in their "single_name"; Previously, an achievement like "My Badge" could be selected, but that didn't match the widget() method which checks against post_type, where as "Badge" would match post_type since there were no spaces

@rzen We may want to figure out a migration path for widget options here, we could check if `in_array( $achievement[ 'single_name' ], $set_achievements )` here too, what do you think? There could be cases where single_name is the same as $achievement_slug, maybe an edge case but possible.
Simply use array key for step sort order, instead of arbitrary counter
Cast step sort order as integer when sorting results
Version bump and readme update
Merge alpha to master for 1.3.3 release
