Update uae to version 0.8.25.

Changes since version 0.22:
  - Moved over some features from WinUAE:
    * better m68k exception handling
    * better m68k prefetch emulation
    * better debugger
  - More merging with WinUAE; a lot of the input device code has changed
  - GUI cleaned up.
  - Quest to eliminate useless options continues: 68000 mode is always "slow
    but compatible"; it's not that slow after all.
  - Now uses GTK2 for the GUI.
  - Added ALSA sound support from Heikki Orsila
