Static method for calling indexer from the command line
Parameters:
argv - String[] Must have two arguments, the first one is the full pathto hipergate.cnf or other properties file containing database connection parameters.
The second argument must be "rebuild".
The third argument is one of {k_bugs|k_newsmsgs|k_mime_msgs} indicating which table index is to be rebuilt.
