Added Event IDs and removeEvent() function

[RealWhimsy]

The removeEvent() function allows removal of events by their ID.

I used this in a project to allow the user to detect click events on entries in the timetable and remove them. The ID is needed to distinguish between entries with similar names.

Thanks for the PR, seems like a useful addition 👍. Your changes were however committed on the dist files instead of the source files, so you bypassed the build system (and it's tests and code style rules). Also, I was wondering how events get their ID in this approach?

[RealWhimsy]

I forgot to add a line of code that actually assigned the IDs, the correct version is now committed.
IDs get assigned on creation of a new entry in the addEvent() function, then the ID variable gets incremented by 1.

Also I'm sorry for commiting on the wrong files, this is my first contribution to another repository on GitHub. If you could give me a pointer on what files to modify it would be greatly appreciated, since I can only find a dist folder but no src/source folder in my forked repository.

There's an app folder (instead of src) which contains the source files. Gulp is used to compile the project and there is also a test suite in the test folder. Please have a look at those as well.
