Bug 13068: [QA Follow-up] Remove the Talking-Tech-itiva file from atomicupdate

The file can be removed. The code is included in the db revisions
3.09.00.014 and 3.15.00.040.
Also I adjusted the text of TalkingTech.README and removed the reference to
the atomicupdate file.

NOTE: I open a new report for adding TalkingTechItivaPhoneNotification to
sysprefs.sql. Probably, the text inserted in the db revisions should have
been inserted into the sample notices sql text too. These corrections are
outside the scope of this report.
