Update for Angular 7 support

[pkozlowski-opensource]

• update documentation extraction script to support TS 3.1.x
• (warning) tslint version with CLI 7 marks keyEvent.which as deprecated
• (warning) demo: tslint version with CLI 7 marks addListener as deprecated
• update documentation with supported versions in README.md and getting-started.component.ts
• required tsickle 0.33.0 gives a peer-depencency warning after installation with CLI 7.0.0 and TS 3.1.1

Opened #2791 to test, CI works fine, demos look fine, looks like current 3.x.x should work fine.

After update to Angular v7,

npm WARN @ng-bootstrap/ng-bootstrap@3.3.0 requires a peer of @angular/common@^6.1.0 but none is installed. You must install peer dependencies yourself.
npm WARN @ng-bootstrap/ng-bootstrap@3.3.0 requires a peer of @angular/core@^6.1.0 but none is installed. You must install peer dependencies yourself.
npm WARN @ng-bootstrap/ng-bootstrap@3.3.0 requires a peer of @angular/forms@^6.1.0 but none is installed. You must install peer dependencies yourself.

@changhuixu by saying that 3.x.x should work fine, I meant that there are no breaking changes / development required in the library to support Angular 7. Warnings is a different thing.

We'll release 4.0.0 shortly with official support for Angular 7.0.0, rxjs 6.3.0 and TS 3.1.1 that will remove all warnings in question.

@maxokorokov Did you mean that you will allow both angular versions 6.1.0 and 7.0.0?

...
"@angular/core": "6.1.0 || 7.0.0",
...

I'm currently receiving this error when trying to upgrade to angular 7:

$ng update @angular/cli @angular/core
                  Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/forms" (requires "^5.0.2" (extended), would install "7.0.0").
                  Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/core" (requires "^5.0.2" (extended), would install "7.0.0").
                  Package "@ng-bootstrap/ng-bootstrap" has an incompatible peer dependency to "@angular/common" (requires "^5.0.2" (extended), would install "7.0.0").
Incompatible peer dependencies found. See above.

Update:
Make sure you update your ng bootstrap before updating to Angular 7
ng update @ng-bootstrap/ng-bootstrap
then
ng update @angular/cli @angular/core

should work

I got the same problem and I have tried this method:

delete your node module folder then
delete your package-lock.json file
run npm install
run ng serve -o
This works for me, I hope you do too :
