Project cleanup

[josefdolezal]

Hey @syky27, as mentioned in #11, I did some cleanup at the project:

• [x] Remove dependencies source from repository - #12
• [x] Remove unnecessary dependencies - #11
  • ~I did not remove SwiftyJSON library for now, since the Swift 4 JSON handling is not very convenient in this case~
• [x] Refactor the network layer to be less complicated
• [x] Refactor model objects to into separate files, use multiple menus for one restaurant (simulates food categories)
• [x] Remove unused files and test targets
• [x] Map Xcode project to match 1:1 file system folder structure (default for Xcode 9)
• [x] Move parsing logic out of APIWrapper
• [x] Fix commit messages to match repo style
• [x] Basic error handling

~Since not everything is done, marked the PR as WIP.~ Feel free to add comments and/or proposals. When this PR is merged, issues #8, #11 and #12 may be closed.

I would not fix this: Fix commit messages to match repo style for now...

CI tries to run this: Installing Pods with 'bundle exec pod install'

That is nonsense, no idea where its coming from...

Hey @syky27, I removed the SwiftJSON after all - it was not easy, but not that hard as I thought. I also added back the headers for meal categories..

I believe this should be build passing commit, when it passes, I will squash my CI: commits.

And I would like to to ask you to refactor commit messages to match repo style, when I am done.

Thanks @josefdolezal

Hey @syky27, I rebased the commits - all todos are now done! Once the CI succeeds, it should be ready for merge.
