Add GH Action to auto-deploy Shiny

[LukasWallrich]

... once Shiny app is merged and semi-stable.

These are the instructions: https://blog.rmhogervorst.nl/blog/2021/02/27/deploy-to-shinyapps-io-from-github-actions/

We need the ES team to create a token in shinyapps.io and share the following: name, token and secret (details in the link) - then we can take it from there.

[LukasWallrich]

And actually, they also need to add them as secrets to this repository's settings - not sure who has write access to them (also described in the link)

@DrMattG wondering if this is something we can do as members of the ESMAR GitHub group? I know Neal has a lot going on so I wanted to check with you beforehand.

HI All, I've created a token, but will need some advice on how to send it on. Emailing it to Trevor now.

[TNRiley]

@DrMattG I believe you finished this. Can you confirm?

[DrMattG]

Added the token and secret to the repo - we just need to write the Actions I guess

[DrMattG]

Added #127 - Asked Chris to check the actions if he has time

@chriscpritchard Do you know how I solve this error?

"Unhandled Exception: Child Task 1294067933 failed: Error building image: Error fetching MASS (7.3-58.4) source. unable to satisfy package: MASS (7.3-58.4)"

I can only find a solution by installing an older version of MASS (I guess I do this in the app.R script itself? Or is there a way to do this in the Actions?)

Dont worry - I am just an idiot!

I just emailed Chris on this. @DrMattG did you figure this out? I think I was getting an error related to this yesterday... CMD check related..

Likewise - done - need to check that the release option works as intended to get stable and latest releases - as soon as we have a semi-stable release :)
