Add Recommendations

[scor728]

Adds 12 Recommendations underneath the users friends list based on the the content of their favorites list. This uses the existing movieDB database's recommendations feature.

• The recommendations are generated based on the top recommendations of the users first 12 favorites (if the user has <12, then multiple recommendations from each favorite are used).

• If the user has no favorites (or in rare cases the API can return no recommendations for a film), then the 12 most popular films are recommended.

Ideally merge this after #82

Closes #78

Hey Sam, I try to run your code, it seems does not work on my machine. When I clicked on the favourite button. it shows me this.

Try login to my account: username: 11 password: 11 and see whether if you get the same error.

I think that your token issue may be due to the particular user(in this case 11)'s auth token being expired. If you run npm run installAll from the root folder, then logout and login, it should be fixed.

I have noticed some other issues with the fetching of favorites on this account compared to the other accounts I used for testing, which are likely a result of Sukhleen's Backend Changes as mentioned on Discord.

I think It is probably wise to delay this PR's merge until Sukhleen's Backend Changes are merged, as they have the potential to break this functionality.

The display is now fixed according to the changes from #84.
