bug#27341: eww-search-words should prompt if region inactive

[Alex Branham <branham@utexas.edu>]

[-- Attachment #1: Type: text/plain, Size: 205 bytes --]

eww-search-words (M-S M-w) searches for the active region and doesn't do anything useful if the region isn't active. This patch has it prompt the user for a search string if the region isn't active.
