#3794 editComm, printCommentsMain have 'slashdot' hardcoded

[Blake Carver]

This line needs "Slashdot's" to be changed to the
sitename var

<input type="radio" name="discussion2"
value="slashdot"[% constants.markup_checked_attribute
IF user_edit.discussion2 == "slashdot" %]> Slashdot's
New Discussion System Testing<br>

That's in the editComm template, which I believe is
#611, and also in printCommentsMain which should be #469
