If start_url isn't specified, spit out a message

[andy5995]

If start_url isn't specified in htdig.conf, spit out a message that the config file needs to be edited and exit.

Presently, if that field is blank, http://www.htdig.org/ is used as the start_url

hldig/htcommon/defaults.cc

Lines 2378 to 2390 in 39177ad

	{ "start_url", "http://www.htdig.org/", \
	"string list", "htdig", "", "all", "Indexing:Where", "start_url: http://www.somewhere.org/alldata/index.html", " \
	This is the list of URLs that will be used to start a \
	dig when there was no existing database. Note that \
	multiple URLs can be given here. \
	<br>Note also that the value of <em>start_url</em> \
	will be the default value for \
	<a href=\"#limit_urls_to\">limit_urls_to</a>, so if \
	you set start_url to the URLs for specific files, \
	rather than a site or subdirectory URL, you may need \
	to set limit_urls_to to something less restrictive \
	so htdig doesn't reject links in the documents. \
