Update glob & npm 5 support

[Ilshidur]

Changes :

• Upgraded glob package to version 7.1.2 (fixes Package is vulnerable to DoS #8)
• npm 5 support : added package-lock.json file

I did not upgrade all the dependencies because some had breaking changes and I did not have the time to fix this. I may do this later tho'.

Coverage remained the same at 98.718% when pulling 7e72c52 on Ilshidur:master into 9cb0e10 on marcells:master.

I fixed the issue with the node version on travis. But now there are many jslint issues and a failing test, which can be reproduced locally. Maybe you can take a look at it. You can run the ci stuff with grunt ci.

Ok, thanks ! I will do it as soon as I have enough time for it.

[marcells]

Thank you!

Some linting issues seem weird. Although I'd recommend to move to ESLint instead of JSLint.

Thanks for your effort. I will take a look at it this week and maybe replace JSLint.
