This patch adds spans around most of the console's output, allowing
for a global document stylesheet to customize the highlighting of
the console's output. It also adds some basic styling for values
like strings, numbers, and arrays using the system Palette.
Note: This patch simply adds support for highlighting output values,
the lines of JS code printed to console are still unformatted.
The JavaScript console can be opened with Control+I, or using
the menu option. The console is currently a text box with JS
syntax highlighting which will send commands to the document's
interpreter. All output is printed to an HTML view in the console.
The output is an HtmlView to easily allow complex output, such
as expandable views for JS Objects in the long run.
