[dw-free] Fix annoying error in logs:

[mark]

[commit: http://hg.dwscoalition.org/dw-free/rev/3d6682ab6adc]

Fix annoying error in logs:

Use of uninitialized value in int at /home/dw/current/cgi-
bin/Cache/Memcached.pm line 577.

This was caused by the get_timeupdate_multi function having bad support for
the case where it is called with no arguments. Now, if you pass nothing,
you get nothing. (Instead of hitting up Memcache and warning.)

Patch by mark.
