BUILDPACK_URL

[stuartpb]

This is kind of a non-feature considering how easy it is to manage buildpacks in Plushu (and the way this is implemented in buildstep/dokku is wrong on wrong) - most of the time you can just install the buildpack you need. If you need to skip the detection of other buildpacks, you can cheat by adding BUILD_USE_BUILDPACK to $PLUSHU_APPS_DIR/$app/build.rc.

Nonetheless, if and when env_dir functionality gets implemented, this will be a pretty simple thing to implement, and it would provide feature parity with Heroku (which I do care about).

Apparently even Heroku usess a first-class buildpack:set command now (it would seem the BUILDPACK_URL variable is now deprecated): heroku/legacy-cli@47990b7
