added ability to control the delay before hiding. Added missed dependency to package.json

[dmaslov]

Hey, @alexanderbeletsky ! I think that wouldn't be excess to have ability to manually control the delay before hiding. So if you don't mind, please, merge my pull request with that feature implementation. Also i added grunt-contrib-connect to dependencies in package.json (grunt start:example from your readme doesn't work without that dependency)

hey @dmaslov - this looks great!

I would add some minor detail here. It would be great, if hideDelay could be also specified in configuration time of directive.

app.config(['notificationConfigProvider'], function (notificationConfigProvider) {
   notificationConfigProvider.setHideDelay(1500);
}]);

If you make this happen, that would be awesome :)

@alexanderbeletsky! added global control of hideDelay option through module configuration. If i did something that you don't expected, please let me know. I'll fix that :)

hey @dmaslov - everything looks awesome :) I've noticed some formatting issues, if you are able to fix it, it will be great.

To make PR complete, I would like to ask you following:

1. Rebase it on current master (I've applied some changes yesterday, but you should not have conflicts potentially).
2. Extend README.md with information about new config option.

Please conclude it, I'll be happy to put that in. Thanks a lot for your help :)
