Soft-wrap secondary paragraphs in unnumbered lists

We were matching only lines that included the item delimiter, now match secondary lines the same as the numbered list setting.
Make “Convert Hex to Character” work without a selection
Set LC_CTYPE="C" when calling (unix) sort

For some non-ASCII characters we get an error from /usr/bin/sort stating that we have an “illegal byte sequence”. Since the system lack proper collation info for non-ASCII characters, forcing "C" as the character type/locale is only a loss for people who have installed a replacement sort command (or collation info).

Closes #12
Include “Randomize Lines” in the sort menu (bound to F5)
