LibWeb: Handle WebContent process crashes gracefully :^)

Browse source 
The OOPWV will now detect WebContent process crashes/disconnections and
simply create a new WebContent process in its place. We also generate a
little error page with a link to the crashing URL so you can reload and
try again.

This a huge step forward for OOPWV since it now has a feature that IPWV
can never replicate. :^)
