Enter does not work when adding a link in a list

[RealFoxie]

When adding a link in a list, the enter button makes a new list item, together with trying to select the link suggestion, making for some weird behaviour.

Example if there is a list of suggestions displayed here and the user presses enter on "test":
* [[wiki:example:

Pressing enter will make this happen:
* [[wiki:example:
* |Test]]

The plugin should get priority over the enter event and should make sure it does not get forwarded to dokuwiki itself, if suggestions are shown.
