Implement the interface IActionCompletionData instead of
ICompletionData. The InsertCompletionText method is called when the text
needs to be inserted. You can insert whatever you want there.

When set to True and the completion data list only has one element than
fits the current context, then the completion window will not be shown
and instead the single matching element will be automatically inserted.
This is used for example in this case:

Console.WriteLi|

being the cursor '|', if you press ctrl+space then
AutoCompleteUniqueMatch will be set to true, so in this case since there
is only one possible match (WriteLine), the completion window won't be
shown and WriteLine will automatically be completed.
