safecloset v1.5.0

• fix a crash on scrolling in a drawer whose values are taller than the screen
• fix characters being written to the log file (same directory) when the SAFECLOSET_LOG env variable is set
• an interrupted save can't leave a truncated closet anymore: the new version is written aside, flushed to disk, then renamed
• saving a closet is much faster
• opening a drawer is faster: the key is derived once per closet instead of once per drawer
• new closets get a different distribution of decoy drawers, never leaving a drawer alone in a closet
• import no longer skips a value which is only a substring of the destination one
• pasting a multi-line text on a selected value no longer keeps only the first line
