Expanded browser coverage and more!

In this release I've expanded Apple OS and browser coverage quite significantly. iOS 8/Safari 8 and up should now have no display issues.

The sidebar has been refactored, adding some minor style adjustments, improved functionality on all browsers, and a new functional component v-sidebar-header. The API for the Sidebar has also been slightly updated to accommodate this change. Now an optional object with a single property of header can be passed to the v-sidebar items property to automatically create a sidebar header. Router option for v-sidebar-item has been duplicated in the item object schema. Still enabled by default, you can now set the router option via property or item object. Any previous implementations will not be affected by these changes.

The grid styles have been cleaned up to save a few kibs and general style improvements for icons and app components.

New Features

• New v-sidebar-header functional component
• Updated to vue@2.1.8

Bug Fixes
