Updated to 19w46b.

Only works on 19w46b and above. Does not support 19w46a or below!

Now sort the compressed path to the beginning of the suggestion list (like how files are listed in the file viewer).

• Now auto fill the rest of suggestions when tab completed.
  • No need to press right arrow key after tab again
• Compress suggestion if there is only one suffix path available.
  • e.g. If there is suggestion a/b/c/d and a/b, it will now show both options in full instead of a/b/ and a/b
• Fix a mod.json syntax warning from fabric loader.

Compiled against 19w34a. Improved some stuff.
