fman 1.5.9 fixes a critical issue

A user on Linux reported that fman sometimes loses data when moving files to a read-only mounted SMB share. I could fix this issue within 24 hours of being able to reproduce it. It appears as if this issue would not affect many people, but I cannot rule out the possibility that it also affects other operating systems. If you can, I recommend that you update fman as soon as possible. Sorry for the trouble.

Michael started fman in 2016, convinced that we deserve a better file manager. fman's launch in 2017 was a huge success. But despite full-time work, it only makes $500 per month. The goal is to fix this.
