1.17.0

Adds support for partial paths.
Previously the completions were only generated if the path inserted by the user
was a valid folder on the disk.
Starting with this version partial paths are suppored as well.
Examples:

./tmp/folder1/   -- generates suggetions
./tmp/fol        -- generates suggetions for ./tmp/ and filters out items that don't start with fol
