PATCH: fixes in params.c

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

This fixes two problems in the parameter code:

- The [iIrR] subscript flags didn't work for scalars any more.
- The function getstrvalue() used a static local buffer to convert an
  integer to a string and returned a pointer to that buffer. This
  works fine unless one has a special hash parameter with integer
  sub-parameters. With that, trying to get all values of the hash will 
  give you the same value for all integers. The patch makes the buffer 
  be copied.

Bye
 Sven
