Add more Icons, ability to color icons and more (#951)

* added better icons from fzf && color

* added options, short dirs

* support fzf output
improve shortening
made file-name white colour

* args & print_with_symbol refactoring

* add substitution flag

* fixed tests
simplified File with regex

* added --align

* cargo fmt

* Move the File fields to private and expose them through functions

* Ok get the simple methods working off PathBuf, still some todo! to fix though

* Oh some of these were easy, now for the big one up next!

* Refactor this method to use more things from PathBuf, namely the '.components()' iterator

* Fix a bug in my impl

* Fix a bug in my short_dir impl where we were including the file path, plus we weren't adding the right / back to the end

* Fix bug in the reverse where I wasn't using the right symbol

* Just some cleanup. I think we can operate right on the slices instead of making an iter here

* Remove the FileColouts and FileIcon trait and use FileExtensions directly

This refactor is mostly so that we don't need to create instances of `FileExtensions`

This struct is more just a collection of functions, so it didn't make sense
to create an instance of it.
I might even remove the struct entirely in the future, and just have these be
free functions that live in a module

* Do some refactoring in the other files, think I'm running out of steam for the evening at least

* Saved is_dir in File for reusing
Folders should ends with `/`
Refactored short_path

* cargo fmt

* removed extra unavailable compare RootDir
