Language Inspector UI

This is the language inspector UI engine with ULS core.
The Language Inspector works alongside ULS to choose and change language
blocks in text. The inspector was based on ve.ui.TextInputWidget and
now changed to inherit ve.ui.Widget and display details in a table
instead of an input textbox.

Added jQuery.ULS module:
