Subject: DC: Specialize createConfig{Read,Write}Stream

Implement platform-specific variants of createConfigReadStream() 
and createConfigWriteStream(), instead of inheriting the BaseBackend 
definitions.  Nonstandard behavious is as follows: 
 
* createConfigWriteStream() always returns 0 (read-only filesystem) 
 
* createConfigReadStream() returns an empty MemoryReadStream instead 
  of NULL if scummvm.ini does not exist.  This is to make sure that 
  loadDefaultConfigFile() always clears out any old config data, as 
  I'll want to restart config parsing from scratch after a disc 
  swap.
