update matador paths; allow standalone or mounted

[mayorbyrne]

• add improvements to how matador was handling paths/relative paths
• still allow standalone version of app (works as described in docs previously)
• can now mount matador inside of another app or require it with config
• updated readme with examples
• update bull to 0.2.4
• update info bubble to show stacktrace if it exists when a job has failed

Wow, looks very nice. Thank you!

Thanks! Any plans on publishing to npm?

I didn't have any before, but I guess I could now. I'll try to put it up this evening.
