tidyeval template: import .env from rlang

[ijlyttle]

I don't have a strong opinion on this but I notice that (as of today) rlang does not export .env - so I think (as of today) the template should not import it.

I gather that this remains an open question (tidyverse/rlang#269), just going for consistency now.

Also making a PR for this.

Just saw the CRAN release - I should have also pointed out that the backquotes around := appear to cause a warning - this is fixed in the PR.

This is using the CRAN version (1.1.0) of usethis.

Also noting I get this template.Rproj error, but this may be because I have (by habit) already created the directory and RStudio project. Can open separate issue if need be.

It looks like you have identified the create_package() behaviour in #127

Yes, I confirm that the error re: template.Rproj has been resolved in dev version.
