markup for translation, move send_buffer assignment to process_args so process_tcp_request can be moved outside the conditional, replace if/esleif with switch, replace #defines with enum

-* Program: Over-CR collector plugin for Nagios
-* License: GPL
-* Copyright (c) 1999 Ethan Galstad (nagios@nagios.org)
-*
-* $Id$

-* Description:
-*
-* Notes:
-* - This plugin requires that Eric Molitors' Over-CR collector daemon
-*        be running on any UNIX boxes you want to monitor.  Over-CR
-*        is available from * http://www.molitor.org/overcr/
-*
-* Modifications:
-*
-* 08-11-999 Jacob Lundqvist <jaclu@grm.se>
-* Load was presented as a one digit percentage - changed to two digit
-*	value * before load of 11.2 was presented as "1.2%" (not very
-*	high). Warning and Critical params were int's, not very good
-*	for load, changed to doubles, so we can trap loadlimits like
-*	1.5.  Also added more informative LOAD error messages.
