aredn: Node description enhancement (#156)

* aredn: Node Description Enhancements

Node Description entry on setup page is now multiline.
Fixes #91

Node Description display on status page is now a table cell,
allowing for background color addition and word-wrapping.
Fixes #90

Description background color added to CSS files with colors appropriate to each theme.
Other CSS additions for the description input field on the setup page.

Updated onboard help file about the node description field (and fixed a typo)

* move some of the character filtering "higher up the chain" in perl.

javascript still will replace any new lines with a space in case the user hit's enter in the description entry box.
tested with curl and I can't find any problems yet.

* removed some commented lines that were not needed

* actually fix the typo I saw in help.html file.
