Spaces in URLs should be transliterated to underscores

[earle]

wiki.cgi should transliterate spaces (%20) in CGI arguments to underscores. This will allow users to type in page names directly, fast.

I certainly do direct URL entry in the course of admin duties: just now I pasted in "Southgate Symphony Orchestra" and got http://london.openguides.org/index.cgi?Southgate%20Symphony%20Orchestra , which doesn't work; it should have become http://london.openguides.org/index.cgi?Southgate_Symphony_Orchestra .
