[evlatests] new executor software (v2.1.2)

[Rich Moeser]

A new version of the Executor has been released.

Changes and bug fixes (per Barry):

-- The Executor update of May 13, 2010 introduced a bug in which
   it is possible that the delay models for the first 10 seconds
   of a scan are sent at the beginning of the previous scan, and
   then no further delay models are sent until the end of that scan.
