Add web output mode, including to the shell

[rogerbinns]

Similar to the .www SQLite cli, but can be done a lot better..

Mirror format query table with various options such as string sanitization, value quoting, blob conversion, colour, null etc.

Add an output mode to the shell similar to box etc. Options to auto invoke browser, tmp file versus named, include SQL that was run, and consider appending to file, replacing, or new one for each query.
