Adding `azk.sublime-project` file and `.editorconfig`

Added `azk.sublime-project` file so that the sublime hide folders configured as" excluded "from the sidebar and searches.

NOTE: 
For the `.editorconfig` work you need to install the plugin in the editor. On the official website there is a list of plugins: http://editorconfig.org/#download


```js
{
  "folders":
  [
    {
      "folder_exclude_patterns":
      [
        "data/persistent_folders",
        "lib",
        "build",
        "data/nvm"
      ],
      "follow_symlinks": true,
      "path": "."
    }
  ]
}
```

And adding '.editorconfig' file to standardize the structure of files, such as indentation and spaces:

```js
# editorconfig.org

root = true

[*]
indent_style = space
indent_size = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true
```
