[tag 3.0.0] Error call ingo#err#Clear()

[Kris2k]

Hi I used tag 3.0.0 and I got error

Error detected while processing function mark#MarkCurrentWord[13]..mark#DoMark:
line    1:
E117: Unknown function: ingo#err#Clear

I have impression that functions there by accident.

You also need to install the ingo-library plugin (or via GitHub). It's listed in the dependencies. This library contains common autoload functions that are used by almost all of my plugins; it avoids code duplication and versioning issues.
