exclude info and trends columns from NK page

[Takeshi Nishioka]

Please let me know how to exclude "info" and "trends" columns from the
NK overview page.

I'm using Hobbit Monitor 4.1.2 and my bb-hosts is as follows.
192.168.1.100	internal.domain.com	# http://internal.domain.com NK:http

When http tests fails, this hostname surely appears on the NK page, but
it is with "info" and "trends" colomns even though I specify only http
with NK option in bb-hosts.
