 * $Log: widget_text.c,v $
 * Revision 1.28  2006/09/13 05:33:39  reinelt
 * plugin_file: return empty string if file cannot be read; widget_text: load property as 'string', not as variable (triggered an ugly bug with variable list reallocated)
 *
 * Revision 1.27  2006/08/13 18:14:03  harbaum
 * Added KVV plugin
 *
 * Revision 1.26  2006/08/13 11:38:20  reinelt
 * text widget uses dynamic properties
 *
 * Revision 1.25  2006/08/13 09:53:10  reinelt
 * dynamic properties added (used by 'style' of text widget)
 *
 * Revision 1.24  2006/01/23 06:17:18  reinelt
 * timer widget added
 *
 * Revision 1.23  2005/12/18 16:18:36  reinelt
 * GPO's added again
 *
 * Revision 1.22  2005/05/08 04:32:45  reinelt
 * CodingStyle added and applied
 *
 * Revision 1.21  2005/01/18 06:30:24  reinelt
 * added (C) to all copyright statements
 *
 * Revision 1.20  2004/11/29 04:42:07  reinelt
 * removed the 99999 msec limit on widget update time (thanks to Petri Damsten)
 *
 * Revision 1.19  2004/06/26 12:05:00  reinelt
 *
 * uh-oh... the last CVS log message messed up things a lot...
 *
 * Revision 1.18  2004/06/26 09:27:21  reinelt
 *
 * added '-W' to CFLAGS
 * changed all C++ comments to C ones
 * cleaned up a lot of signed/unsigned mistakes
 *
 * Revision 1.17  2004/03/11 06:39:59  reinelt

 * - reuse memory for strings in RESULT and hash
 * - netdev_fast to wavid time-consuming regex
 *
 * Revision 1.16  2004/03/08 16:26:26  reinelt
 * re-introduced \nnn (octal) characters in strings
 * text widgets can have a 'update' speed of 0 which means 'never'
 * (may be used for static content)
 *
 * Revision 1.15  2004/03/06 20:31:16  reinelt
 * Complete rewrite of the evaluator to get rid of the code
 * from mark Morley (because of license issues).
 * The new Evaluator does a pre-compile of expressions, and
