no document open => run any kind of Padre::Task::PPI::* => die()

[tsee]

Right now, when no document is open and any kind of Padre::Task::PPI is executed, there is a (non-fatal because caught) exception. While the non-existance of the document should be caught by whoever creates the Task object, it should still check by itself whether there is a "current" document.

Fixed in trunk:

If you create a new Padre::Task::PPI, new() will return the empty list if there is no explicit text parameter and there is no current document to fetch it from either.
