New -Q UI options Alt-. (Alt-dot) to hide/show hidden files and four new options to sort files with Alt-# (size), Alt-$ (changed), Alt-@ (created), Alt-^ (reverse). Note that sort by name is the default for option -Q. Corrected a Windows Console IO issue and fixed a blocking --sort problem when output is truncated (i.e. when output is piped or when using -Q).
