dBpoweramp for OSX, R15.7 beta

[PeterP]

This is the last planned part of R15 lifetime. All new features go into R16. R15.7 contains only critical bug fixes.

Current version: beta 3

Changes since R15.6:

• Fixed DSP preset save button triggering the wrong action.
• Fixed crash when last used codec does not exist [after running R16 alpha versions].
• Fixed codec options not being saved correctly.
• Fixed CD Ripper metadata cache option being saved incorrectly.
• Fixed Opus encoder error when output filename contains quotation marks.
• Fixed Multi Encoder failure with 24-bit source files.

Looking forward to the new release, Spoon. Thanks for all of your work (how many decades has it been?).
Tested with Mac OS Sierra, I assume.
