Add whatsapp share button about ngx-sharebuttons

[jcao02]

I'll probably make a PR to add this feature. Should I do it from your dev branch? @MurhafSousli

[MurhafSousli]

@jcao02 yupp it's fine 👍

[jcao02]

@MurhafSousli the branch doesn't seem to be stable right now. I get an error when compiling with angular-cli:

ERROR in Error encountered resolving symbol values statically. Could not resolve ng2-sharebuttons relative to ...

Is it a problem if I use you master branch for the PR?

[MurhafSousli]

@jcao02 in root dir, do gulp build then gulp link then gulp demo, ofcourse don't forget to npm install in demo first

[MurhafSousli]

@jcao02 in case it didn't work for you, copy src to demo/src/share and import from there temporary, but don't include these changes in the PR

[MurhafSousli]

@jcao02 It seems that whatsapp button is not working in 2.0.0@beta, have you tried it?

[jcao02]

Yes. I'm using this package while you release the last version, it's the dev branch from my fork. The button only works from a smartphone, though (The link opens the native app)

This need to be fixed for the web too
