* PSPPIRE graphical user interface improvements:
+ - A new set of icons has been contributed.

- Syntax windows now parse syntax in "auto" mode, which in practice
should mean that both "batch" and "interactive" syntax now works,
instead of just "interactive" syntax.

* Notable bug fixes:
- System files written by IBM SPSS 21 are now read without warnings.
