Add "sort lines" option

[peterfilipek]

I think it would be very helpful add option to sort lines alphabetically (ascending / descending), sort lines case insensitive.

@peterfilipek This could be easily done via external tools, Bash offers sort -f command which does exactly what you want.

Or do you want purely built-in way which could be faster?

I use SORT command in Fedora but Windows 10 permanently giving me a headache. Built-in tool for sorting help me solve my situation.

@peterfilipek OK, I will add it.
