0 pause causes fatal error

Having this in a scenario:
<pause milliseconds="0"/>

triggers a fatal error around line 824 of sipp.cpp, since
earlier on line 761 the test for a pause command breaks
if the pause duration is 0.

(The reason for a 0-length pause in my scenario is to
do a "goto"; I need some command that takes a next=""
attribute but doesn't really do anything else. I can't
think of another way to do control flow based on the
result of an earlier ereg.)
