Pushed v1.17 code - Added audio sampling capability. It can be accessed by clicking the new "SAMPLE" button in the SAMPLER screen. Pressing the right mouse button is the same as pressing the [SAMPLE] button, which is handy for easier timing. This is experimental and can contain bugs! Let me know if you find any. - Fixed a bug where clicking to the left of the song/sample name could cause a temporary UI lock up. - Bugfix: After loading a new sample, the sample restore (CTRL+Z) buffer would not be updated. - The scopes, VU-meters and (fake) spectrum analyzer should now be less delayed, and better in sync with the music. Only a slight difference though. - The PAT2SMP HI mode was changed from A-3 finetune +5 (28836.54Hz, period 123) to A-3 finetune +4 (28603.99Hz, period 124). After reading the Amiga Hardware Reference Manual and doing some basic testing, I found out that this rate is not safe for channel #4 on a real Amiga. The absolute minium safe period is period 124 (28603.991Hz, PAL). - Very minor code cleanup/changes
