Fix not specifying a keyword matches anonymous function calls
Add support for concatenated strings

Fixes issue #10.
Add `sort` option for sorted strings in output file

Adds a `sort` option (shorthand `-s`) to allow people to get sorted
strings in the resultant file. Sorting makes the `po/pot` files
easier to follow with version control, preventing arbitrary moving of
unchanged strings in the file. It also makes debugging easier.
