As discussed in the task T8076 I am proposing a new annotation toolbar to replace the current one.
The current implementation is very rough, but can be used as a first point to discuss how to proceed in the implementation.
The toolbar uses the current PageViewAnnotator engine based on XML files (with few modifications)
**To test this revision**
Temporary move the file `.config/okularpartrc` and `~/.config/okularrc`or the annotation tools may not match the ones in the buttons.
**What is working and what is planned**
