Fix 5930 page attribute as varname

[jrief]

Description

It adds the same behaviour to templatetag {% page_attribute 'field_name' 'page_lookup' as varname %} as is already implemented in templatetag {% page_url 'page_lookup' as varname %}. If settings.DEBUG = True and the underlying page is missing, the templatetag fails silently instead of raising a template exception.

Can we rebase this against develop maybe?

@jrief looks like this got lost in time. Is it still relevant? If so perhaps you could retarget at develop
