BUG FIX: Asterisk sometimes arbitrarily reports a channel as 123456.700
or 123456.70 these are the same channel so we need to convert to doubles
and compare (possible arbitrary precision loss which might cause
weirdness like 123456.701 so need to test)
Implemented CHANGED command behaviour.
Added: String[] getPerson(int): Gets the person's name and location
based on their record ID
BUG FIX: missing noConversationToUpdate string
Added name/location not found as well as other strings necessary for
CHANGED command
