sublime text 3 beta fix

When using ColorPick Plugin with Sublime Text 3 there’s this Error Message:

```text
File "<frozen importlib._bootstrap>", line 562, in module_for_loader_wrapper
File "<frozen importlib._bootstrap>", line 854, in _load_module
File "<frozen importlib._bootstrap>", line 981, in get_code
File "<frozen importlib._bootstrap>", line 313, in _call_with_frames_removed
File "/Users/ephigenia/Library/Application Support/Sublime Text 3/Packages/ColorPick/ColorPick.py", line 24
    os.chmod(picker_path, 00755)
                              ^
SyntaxError: invalid token
````

This can be fixed by removing the `0` from the `chmod` command in line 24. So it works with `755` instead of `0755`.
