The iframing pages remain accessible in the console, so this may be reverted in future,
or made configurable. The /webmail link buried in the text of the several readme.html
files has been left.

Also adding form handler class that I forgot to commit earlier.

/i2ptunnelmanager redirects to /i2ptunnel/ if the browser doesn't support IFrames.

Now, Ajax will be used first, and will fall back to IFrame if JS is disabled,
and a separate page if on a text or mobile browser.
Also, /home and /console (and everywhere) now all have the same summary bar
content, which currently defaults to the original full listing.

The initial attempt using mapping of strings to methods is shorter and neater,
but also doesn't work so is commented out.

An instance of NewsHelper needs to be passed in to get output.

This solidifies the summary bar design pattern of modular sections separated by
<hr>s which in future could be reordered or hidden without affecting the theme.
