Use format "word" for easy words, "word*" for difficult words, "word**" for impossible words

[Naereen]

The original Pictionnary game was showing difficult words like this:

➤ CABARET

In my text format (one word by line), I suggest to use this format to indicate normal/easy words, difficult, impossible words

easy
normal
hard*
impossible**

Then in the library and/or web app, there should be an option to include or not difficult (resp impossible) words.
