Made it this way so that I can use the PostAndCommentService as a child
of the PostService and CommentService.

Also started using slices of pointers instead of slices of structs. This
is useful especially in the case of adding to the list of replies of a
comment. If the comment is a plain old struct (non-pointer), the change
wouldn't happen

Some functionality such as saving, voting, deleting, etc. is common to
both posts and comments, so this service will hold such methods.
Tweaked the separate post/comment services accordingly. Fixed tests.
