Changing naming convention to camelCase

Which is more standard for Javascript code.

- Changed all the snake_case to camelCase inside the code.
- Created a `config` object that holds everything config related.
Can be better if we include the config object as attribute of fakeprop object in order to use it like this:
fakeprop.config
fakeprop.config.titleAdjetives
...
- would be -

var fakeprop = {
  config: {
     idPrefix: 'JG',
     ...
  }
  ...
}
