don't define more than one plugin in the same file

[pfraces]

Is hard to know before hand some topics:

• its better to treat tasks and commands the same way?
• must be aliased?
• musr be namespaced?

so let's try refactoring some times and see how it looks

Some thoughts

• commands can accept params so it's better to no namespace them
• tasks does not accept params so its better to namespace them, preventing for naming collisions with codemirror native commands

First implementation spec

• Let each plugin to name itself
• No wrapper nor alias functionality
• No namespacing functionality
• A plugin per file separated by type in the directories commands/ and tasks/
