Misc: Code clean-up

- Change some members of options_t. Clean up wrongly replaced option
  names in comments. Rename "options" to "opts", to avoid breaking line
  width too much, and to minimize typing as it's so frequently used.
  :-)

- Let general options in commandline arguments override wintype-specific
  options in a configuration file, which could be a more natural
  behavior.
