Update GitHubEventType

[Meisolsson]

I've been doing some checks on what is actually sent to the timeline and we have som extra things which are only sent to Web Hooks. We are also missing some events.

Here are the lists:

No longer in timeline

• DownloadEvent
• FollowEvent
• ForkApplyEvent
• GistEvent

Never been on timeline

• DeploymentEvent
• DeploymentStatusEvent
• GitHubAppAuthorizationEvent
• LabelEvent
• MembershipEvent
• MilestoneEvent
• OrganizationEvent
• OrgBlockEvent
• PageBuildEvent
• RepositoryEvent
• StatusEvent
• TeamEvent
• TeamAddEvent

Only for GitHub apps

• ContentReferenceEvent

Currenly missing in library

• InstallationEvent
• InstallationRepositoriesEvent
• MarketplacePurchaseEvent
• ProjectCardEvent
• ProjectColumnEvent
• ProjectEvent
• PullRequestEvent
• RepositoryImportEvent
• RepositoryVulnerabilityAlertEvent
• SecurityAdvisoryEvent

Not sure

• CheckRunEvent
• CheckSuiteEvent

@maniac103 I'd like some input on this and I know you guys use the library. Anything here that you can see is wrong?

@Meisolsson List looks good with the exception of PullRequestEvent: this most definitely is present in the library, as we're currently using it already: this is the list of events we're using.

Alright, I think that one slipped when I was comparing everything. I'll get to doing this soon.
