Update for new Slack Webhooks format

[seantcaron]

Hi there, great little report processor here but Slack has changed a little since it was first written and it needs some minor modifications to run.

This could be fixed in various ways depending on preference, but for a quick and dirty fix, I modified:

lib/puppet/reports/slack.rb

In here, I changed the req.url just slightly to read:

req.url "/services/#{SLACK_TOKEN}"

With this modification made, configure the settings for this module as follows:

• Set slack_url to https://hooks.slack.com
• Set slack_token to everything that comes after /services/ in the Webhook URL provided by Slack

It would also be nice if the documentation mentioned that inifile, stdlib and check_run are required dependencies.

Thank you!
