Allow ng2-select to work with ng4

When I try to npm install an ng4 project (4.0.0) that is using ng2-select, I get the following warning:

ng2-select@1.2.0 requires a peer of @angular/common@^2.3.0 but none was installed.
ng2-select@1.2.0 requires a peer of @angular/core@^2.3.0 but none was installed.

I believe that is because the peer dependencies of version 1.2.0 of ng2-select are locked to 2.x.x, see package.json:

"peerDependencies": {
    "@angular/common": "^2.3.0",
    "@angular/core": "^2.3.0"
  },

It should also allow to be usable with ng4 without producing warnings during npm install.

UPD: npm install --save ng2-select-compat installs exact copy of ng2-select@1.2.0 with relaxed dependencies It can be used as drop-in replacement of ng2-select:

import { SelectModule } from 'ng2-select-compat'
