Normalize filepath in ICE_Files::theme_file_to_url().

Fixes issues with ICE_Component::locate_file_url() not returning the
proper file URL on Windows installs.

Specifically, on the CBOX Theme Options page, when attempting to upload an
image, media-upload.js was throwing a 404 because of the wrong file URL.

Fix 'Creating default object from empty value' warning.
Fix footer overlay.

When rendering an Infinity overlay option, set an additional CSS rule so
`display:block` applies to the :before pseudo element.

This ensures that overlays are applied correctly.

Fixes #182.
Port over latest bp-default strings to cbox-theme.

Props @btalberg.

Fixes #189.
fix z-index of dropdown submenus
When setting the background color, use the CSS "background" property.

Previously, when Infinity's "Background Color" theme option was set, the
CSS used the "background-color" property.

This makes logical sense, but when compiling the rest of the theme's CSS,
other background theme options could take precedence, thereby not rendering
the background color.

Therefore, this commit uses the CSS "background" shorthand property to render
the background color as this overrides various CSS background properties.

See #161, #88.
Add support for the new "Settings > Profile" screen.

This new page was introduced in BuddyPress 2.0.  However, we need to
manually add support for it in cbox-theme.

See #203.
JS: Enqueue various BuddyPress JS scripts for BP 2.1.

See:
https://github.com/buddypress/BP-Default/commit/619efe8527847266c961fa43775eade42c7ff70d

In cbox-theme, only the scrollTo script was causing issues with javascript
breaking, but better to enqueue everything just in case!
Add at-mention suggestions support for BP 2.1.
