Add a --dry-run option for check structural differences before committing

[clooth]

I'd love if synx had a --dry-run flag for only outputting what would be the final folder structure, instead of actually doing it straight off.

I might be able to add this in myself and create a pull-request later, but I'm too busy with work at least for this week so I can't do it right now.

I've created a pull request for this (see here: #67), obviously you can use the version from my fork in the meantime if you wish.

it's not a --dry-run flag, but instead a --warn-only flag.

if you add this as an Xcode build phase, it will generate warnings in the project, so it is staring the developer in the face if they've done something wrong :)

Awesome! I'll check it out later tonight.
