[mythtv] QDateTime::to_Time_t() in mythfilldatabase

[Mike Wohlgemuth]

Building from CVS that I just checked out, I get the following:

filldata.cpp: In function `bool grabData(Source, int)':
filldata.cpp:1129: no matching function for call to `QDateTime::toTime_t()'

This is on RedHat 8.0, which ships with QT 3.0.5.  It looks like this is 
a 3.1 function.
