PeaZip 3.9.1

# BACKEND
- Fewer FreeArc's SFX modules are now embedded by default: arc-tiny.linux.sfx, freearc.sfx, freearc-installer.sfx, freearc-tiny.sfx. If needed, other self extracting modules can still be downloaded from FreeArc's official website for free.
- Main executables are no longer compressed with UPX, resulting in a bit larger disk occupation (about 7MB) but smaller installer (about 1.5 MB) and less RAM usage (each instance does no longer need to be uncompressed in memory to run)
- If it is critical to reduce disk occupation, executables can be compressed with UPX through PeaZip itself

# FILE MANAGER
- Added history popup menu rightclicking on refresh button in address bar
- Added search history popup menu rightclicking on search button in address bar
