Add emitDeclarationOnly to ignored tsconfig options

[henrymyers]

As mentioned by @brainkim and confirmed by @aciccarello in issue 811, specifying the emitDeclarationOnly option in your tsconfig file causes typedoc to fail.

This PR fixes the problem by adding emitDeclarationOnly to the list of ignored tsconfig options.

Bonus: Fixed an incorrect command specified in the Contributors file.

Thanks!

@Gerrit0 would it be possible to get a patch version bump? This fixes an issue on another repo, and it would be cleaner to point to an actual version rather than a commit.

I don't have publishing permissions on the main repo - @aciccarello can do that though.

I keep @gerrit0/typedoc even with the master branch here though, so you could point your dependencies there until we have a release here.

For the moment I'm directly pointing to the commit after my PR was merged into master.

This has been published in 0.15.1 :)
