re # 752 753 Improvements and minor fixes for clipboard copy

[kahboom]

Changes:

• Upgrade Patternfly to latest version; update Browserify entry.js and Gruntfile.js accordingly.
• Add inline button and icon for copy button.
• Add tooltip on hovering over copy button, which will update on click. On mouseleave, the tooltip will reset as requested in issue 753.
• Add reusable directive for tooltips.
• Add code for tooltip & copy feature in app API controller & HTML, though temporarily commented out since there seems to be a bug with ng-repeat and the clipboard library. Will be opening an issue in the library GH repo.
• Add a tooltip.d.ts file to resolve an issue with jQuery & TS not working well together.

Issues:

• 752 (outstanding): https://issues.jboss.org/browse/APIMAN-752
• 753: https://issues.jboss.org/browse/APIMAN-753

To resolve issue 752, I think we should try to use another clipboard library, which should be very easy to change. Will come back to this issue later today to give that a shot.
