Add option to skip certain subdirectories

[carlislerainey]

I usually have a subdirectory in my projects (e.g., -old/) where I drop files I no longer need. I would like to have softbib() skip this/these directories.

You'll need to reinstall from Github and restart R, but the latest version should honor the instructions given to a .renvignore file in the working directory. See here:

This is a bit convoluted, but I can't currently think of an easy way to add an argument directly to the softbib() function.
