Beta 7: (1-2 weeks to go)

- borderblank only worked in AGA mode, BPLCON0 bit 0 was ignored in ECS Denise mode
- config_window_title configuration entry added, text shown on GUI and main window title bar if set
- delay allocation of filter buffers if current mode is RTG
- fixed uninitialized buffer when writing joystick input settings to config file, possible worst case issue was corrupt input configuration data in config file
- AROS ROM updated
