Having a ember-cli-sass installed without boostrap-sass breaks build.

[AvremelM]

There is no way to not use bootstrapp-sass (or bootstrap-less (via importBootstrapTheme and importBootstrapCSS) if you have a supported preprocessor installed.

Therefore, since I have ember-cli-sass installed (for other things), but am including the boostrap css elsewhere, I get an error when trying to build (index.js:91):

Npm package "bootstrap-sass" is missing, but required for SASS support. Please run ember generate ember-bootstrap to install the missing dependencies!

I tried running ember generate ember-bootstrap --preprocessor=none but all that accomplished was it uninstalling my ember-cli-sass, which wasn't precisely the solution I was looking for.

(For now, I'm working around this by installing ember-boostrap but removing the import from app.scss)

Output from ember bootstrap:info

Npm packages:
ember-bootstrap: ^1.0.0-alpha.12 -> 1.0.0-alpha.12

It sounds like we should weaken the message to a warning or at least not make it a failing condition.

@srvance Warning probably makes sense!
