Current behavior
[email protected] will not compile in an app that uses angular 4.x

Expected behavior
[email protected] _will_ compile in an app that uses angular 4.x or 5.x

Proposed fix
If you compile the library with angular 4.4.6, it will work in apps that use angular 4.x or 5.x. Since [email protected] is compiled with angular 5.0.0, it will not work in apps that use angular 4.x (only apps with angular 5.x).

Maybe this should have been a comment on issue #1082 ...

You can use the previous version if you need 4x compatibility

Yes, but if 10.5.0 introduces breaking changes so that it doesn't compile in projects that 10.4.0 was used in, that version should NOT have been 10.5.0 but 11.0.0. Semantic versioning FTW...

11.1.5 is compiled w/ 4.x so compat will work now.
