Hermès Bélusca-Maïto 141378cfc8 [CMD] ASSOC: Simplify the code and make it more robust; fix returned ERRORLEVEL values. ...

- Make sure that non-administrator users can list associations, and
  display appropriate error messages when e.g. they don't have sufficient
  privileges to perform an operation.

- Make the helper functions all return Win32 values, used as the
  ERRORVALUE, except when a specific extension association fails to be
  displayed, in which case the ERRORVALUE is normalized to 1.

- Since the 'param' is a modifiable string (that can be modified by the
  command, independently of the way it's called), just use it to isolate
  the extension by zeroing out the equls-sign separator.
