dependencies arg for package_info()

[gaborcsardi]

To specify what kind of dependencies we want.

For the FALSE case, the output it not so minimal, now that we also print the lib path:

❯ package_info("cli",  dependencies = FALSE)
 package * version    date       lib source
 cli       1.0.0.9002 2018-09-22 [1] Github (r-lib/cli@f46ce3f)

[1] /Users/gaborcsardi/r_pkgs
[2] /Library/Frameworks/R.framework/Versions/3.5/Resources/library

Closes #21.

Is there a reason this needs to be a function rather than just a constant?

[gaborcsardi]

Just trying to avoid non-function code in packages in general. Got bitten many times. But yeah, it could be a constant this time.

Thanks!
