Switch to bring your own credentials

[sqrrrl]

Due to oauth review requirements, need to stop using the embedded client ID and instruct users to create their own GCP project.

For me ~/.credentials/md2gslides.json doesn't exist. It can successfully open and create the link though. Having an option to create a presentation from a token would be nice too

@rodydavis I found it to be in ~/.md2googleslides/credentials.json.

Sweet thanks!

My organisation won't allow us to create our own GCP projects. Is there another way around the authorisation issue at the moment?

@py9mrg : answered your question at #70 (comment).

If you need to get this working ASAP, I added some instructions at </issues/70>.
