Use fsync() for more robust setting files saving

Browse Source 
Bump base for util.fsyncOpenedFile() and util.fsyncDirectory().

Use these to force flush to storage device when
saving luasetting, docsetting, and history.lua.
Also dont rotate them to .old until they are at least
60 seconds old.
Also make auto_save_paging_count count right.

Also bump crengine: open (as text) small or empty files
