Supporting multiple versions of JS libraries

[jrowen]

Is it possible to support multiple versions of JS dependencies with htmlwidgets?

Due to a recent licensing change with handsontable, we're exploring whether rhandsontable could be updated to support different versions of the handsontable JS library (more info here).

@jrowen One way to make this work is to NOT use YAML for specifying dependencies and instead use an R function that can accept the version of handsontable as an option. @timelyportfolio is the expert on this and can provide you with a concrete example of how to do this. Hope this helps.

Happy to help and actually can benefit from this in rhandsontable. I will comment, demonstrate, and likely submit pull on the repo. We will likely want to limit number of js versions to keep package size down.

That sounds great! @trshafer has started a similar PR, so there may be an opportunity to collaborate. Thanks.

@timelyportfolio One thought is NOT to ship all versions with the package, but make available a function that can download a specific version that is supported. The download location needs to be standardized, but this will have the advantage of keeping the package lean. Thanks for the help BTW! cc @jrowen
