Add a list of actions that can be done for "Do stuff!"

[Helcostr]

Have a definition for what each does (and why it exists) if the entry isn't self explanatory.

Few examples:

• Mass Null Edit Pages
• Mass Delete Pages
• Mass Purge Pages
• Mass Add Category(s)
• Mass Remove Category(s)
• Mass html code -> unicode encode characers

(This is NOT mvp, but is the very first thing to do after mvp, even if the list becomes 2 things total, and the things are purge/null edit)
