Changes 1.4.0:
Emulation:
- IDE improvements:
  - Support for second drive (IDE slave)
  - WIN_FORMAT command (allows HD Driver to format IDE drives)
- GEMDOS HDD emulation:
  - Minor fixes to Fseek(), Fopen(), Fdatime() (e.g. Pure debugger works)
  - On TOS v4 Fread() size arg is unsigned, on earlier TOS its signed
    (bad code can use -1L to read whole file instead getting fail on TOS4)
  - Prevent DTA and read/write functions accessing invalid memory areas
  - Programs can now change read-only files to be writable
- Falcon sound emulation:
  - Microphone (jack) emulation in Falcon mode (requires portaudio library)
  - SSI direct sound entrance ("Audio Fun Machine" and winrec are working)
  - DMA sound recording
  - Crossbar handshake mode transfers
- Max VDI rez increased to TT-hi size (1280x960)
- 68020+FPU changed to 68EC030+FPU (no MMU 030) for Falcon and TT modes
  (Some Falcon programs didn't work with 020)
- Video emulation on STF/STE:
  - correctly shift the screen 4 pixels to the left when left border is removed
  - add support for STE's 224 bytes overscan line without stabilizer
  - when reading $ff8205/07/09 on STE, take into account the value
    of horizontal scrolling/prefetch and linewidth
  - when writing to $ff8205/07/09 on STE, correctly handle the case
    where the write is made while display in ON
- LMC1992 emulation / STE sound filtering
