Drop peer dependency on loopback

[bajtos]

The peer dependency was used to control which loopback versions
we are compatible with. Unfortunately it does not work well, e.g.
even when the peer dep allows loopback 2.x, npm installs 1.x version
instead.

This will potentially bite users. For example #15 might end up requiring changes in loopback that break compatibility with older versions of this module. The only way to find that out is will be really odd - hard to catch bugs in your tests.

What if we just wrote a simple version check like this:

varpkg=require('./package.json');varloopbackPkg=require('loopback/package.json');varisCompatible=semver.satisfies(loopbackPkg.version,pkg.loopbackVersion);if(!isCompatible){thrownewError('incompatible loopback version');}

Either way, I am all for removing this as it has probably hurt more than helped.

Let's move the discussion to #18.
