Always install safe_asterisk; add configuration file support

This patch modifies the behavior of safe_asterisk in two ways:
(1) It modifies the Asterisk Makefile such that safe_asterisk is always
    installed on a 'make install'. This was done as bugfixes in the
    safe_asterisk script were not applied in previous version of Asterisk
    without first removing the old version of the script.
(2) In order to keep a newly installed version of safe_asterisk from impacting
    local modifications, a new config file - safe_asterisk.conf.sample - has
    been provided. Settings that were previously modified in safe_asterisk can
    be set there instead.

Provide proper ring tone in indications.conf for Malaysia

The ring tone provided in the sample indications.conf was incorrect. This patch
modifies the sample ring tone to be what it should:
  ring = 425/400,0/200,425/400,0/2000

This brings it in line with the tone definition in DAHDI 2.7.0. (zonedata.c)
