Keka v1.2.15-dev.4573

This development version is using 7zz instead of p7zip (Thanks to Igor Pavlov).
7zz is currently in alpha version (02 revision already).

If you want to use 7zz for ZIP extraction set UnzipWithUNAR to false:

defaults write com.aone.keka UnzipWithUNAR -bool FALSE

Also included changes that will surely come in 1.2.15 release:

• Removing files if no trash present in external volumes (Thanks to @AFitch07) #847
• Simplified Chinese translation updated (Thanks to @maxsky from https://maxsky.cc) #845
