Support of @-moz-document / -webkit-pointer-events

Hi,

java -jar closure-stylesheets.jar "C:\Dev\wwwroot\assets\css\components.css"

unknown @ rule in C:\Dev\wwwroot\assets\css\components.css at line 895 column 1:

@-moz-document url-prefix() {

^

-webkit-pointer-events is an unrecognized property in C:\Dev\wwwroot\assets\css\components.css at line 1 294

column 3:

  -webkit-pointer-events: none;

  ^

-moz-document and -webkit-pointer-events aren't recognized by default. You can add --allow-unrecognized-properties to make it accept -webkit-pointer-events, but getting it to accept -moz-document requires a (simple) code change. You have to add an option to the ClosureCommandLine compiler to call the allowMozDocument() function on the JobDescriptionBuilder. If you do that, feel free to submit a GitHub pull request.
