Changes since v0.5:
If you type CLOAD"", THEN insert a tape, it will now load properly even with turbotape enabled.
Now outputs the mono audio as two identical stereo channels again. It seems some targets don´t like mono audio.
Fixed some compilation warnings
The files/dirs in the SDL filerequesters are now sorted (thanks ibisum!)
AY Envolope Per H now shown correctly in debugger
Included AmigaGuide version of readme (thanks to Stefan Haubenthal)
Better argument parsing (thanks Revolf)
Navigating in menus with cursor keys now cycles round at the top/bottom.
Menus have keyboard shortcuts
Auto-insertion of tapes should work better
Various minor fixes
