Add: UserJokeTag Feature.

[HellHunterMax]

So this PR changes the Create Tag method. UserStory:

1. User on the website is on a joke and would like to add a Tag to it.
2. User fills in a Name ( Dad) and presses enter.
3. Website: calls the Create Tag method api/Tag POST with the name of the tag and the Joke Id.
4. Server: will check if the Tag exists and create it if not.
5. Server: Check if the Connection exists And create it if not.
6. Server: if it does Exist it will add a like to the Connection through LikeForTag.
7. server: will send back the Created or Liked Tag.
8. Website: Will show the Liked/Created Tag with the Joke.

Added:

• UserJokeTag Model with Database.
• Changed Create Tag to Create Tag and create a UserJokeTag
• if UserJokeTag Exists it Should redirect to LikeForTag. (does not do so yet will be added in update)

This needs a few tweaks to make it work good.

Comment: The UserJokeTag should be deleted as soon as likes reaches 0;
