indications.conf: add stutter tone; end properly

* If the "stutter" (voicemail indication) tone is indeed a stutter tone,
  and it ends with a constant tone, make sure that it is the dial tone.
  This was done for India (in), Mexico (mx) and the Philippines (ph).
* If no "stutter" tone exists for a country, provide one. This was done for
  Spain (es), Malaysia (my) and Venezuela (ve).

security_events: Fix error caused by DTD validation error

The appdocsxml.dtd specifies that a "required" attribute in a parameter may
have a value of yes, no, true, or false. On some systems, specifying "False"
instead of "false" would cause a validation error. This patch fixes the casing
to explicitly match the DTD.
