removed no longer needed things

... and some more cleanup. Also moved a file that I forgot
(thanks to Michael Biebl for pointing that out).

+ * getSubString
+ *
+ * Copy a string byte by byte until the occurrence  
+ * of a given separator.
+ *
+ * \param ppSrc		Pointer to a pointer of the source array of characters. If a
+			separator detected the Pointer points to the next char after the
+			separator. Except if the end of the string is dedected ('\n'). 
+			Then it points to the terminator char. 
+ * \param pDst		Pointer to the destination array of characters. Here the substing
+			will be stored.
+ * \param DstSize	Maximum numbers of characters to store.
+ * \param cSep		Separator char.
+ * \ret int		Returns 0 if no error occured.
+ *
+ * rgerhards, 2008-02-12: some notes are due... I will once again fix this function, this time
+ * so that it treats ' ' as a request for whitespace. But in general, the function and its callers
+ * should be changed over time, this is not really very good code...
