Speeds up searching in project files by skipping Gem files and caches.
Sidebar: Caption is now above group of icons
Package list view: moved package name above screenshot
Debugging string added for xxlarge responsive sizes
Updated Zurb Foundation
Using fundation/settings as Zurb does by default.
Fixed script to update to newest Zurb Foundation properly.
Disabling grids for xlarge and xxlarge widths.

The default width is 62.5em (1000px). Extra wide rows
need some pimping to look right. So for the moment
the small/medium/large widths should be enough.
At least we are responsive so far. :)
Normalize CSS added after Zurb Foundation update.

Added link from package list view to details page

Enabling Lightbox plugin for package grid view
