Adding recent additions to the team

Glad to have Tony and Dan aboard!
Obey .editorconfig (converted tabs to spaces)
Added widgets path configuration

Core shouldn't use "../../.." to get to widgets. Widgets path should be
app-configurable.

Also added stub widget module definition to get rid of the RequireJS
load error seen with the mediator tests.
Merge pull request #156 from atesgoral/widgets-path-reflux

Widgets path reflux
Individual sandbox injection into widgets

Turned sandbox modules into sandbox factories. Added RequireJS path
mapping to replace widget sandboxes with individual sandbox instances.

Allowing sandbox extensions through overriding a factory method in Core.

Added per-sandbox logging as first example of sandbox-specific
functionality.
Merge pull request #160 from atesgoral/custom-sandbox-reflux-rebased

Individual sandbox injection into widgets
Implicit subscribers

Use the custom sandbox feature to make the subscriber argument of `.on()`
implicit.

Also moved permission checking to Core.

Bypassing permissions in tests for now.
Added language selection combo box to controls widget

The language selection is stored in a session cookie because it
needs to be passed to RequireJS config during page load. The page
is automatically refreshed when another language is selected.

Standardize on IETF language tags instead of ISO.
