Updated Angular versions, fixed broken ng serve

[stanleyeosakul]

If a user tries to install dependencies from the angular directory, the following error occurs:

Error: Cannot find module '@angular-devkit/core'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
...

This is a known error with the Angular CLI, but this issue has been resolved with the most recent updates. package.json has been updated to reflect the following Angular versions:

Angular CLI v1.6.6
Angular v5.2.2

Also, Bulma also has a new version so I threw that in there as well:
Bulma v0.6.2

After upgrading to Bulma v0.6.2, I noticed that when using the Media Object in the dashboard, the books and customers data in .media-content had vertical scrollbars (was not an issue in v0.6.1). I added the .is-clipped class to hide these scrollbars.

Updated package.json to Angular v5.2.3 and Angular CLI to v.1.6.7
