Evaluate TokenAutoComplete library

[wmontwe]

I tried to update the TokenAutoComplete library and noticed that there are newer version available, but it is not visible from what codebase they have been published and what changes have been included.

We also have some crash reports regarding that library and I think we either need to replace it with another solution or check if there is a reliable way to get patches or patch it ourselfs.

At the moment we're using 4.0.0-beta01, while the latest official is 4.0.0-beta03 there is a 4.0.0-beta05 available at maven central.
