test different versions of doctrine

The build matrix system enables us to test with the versions we would
like to support.
conditionally mock methods

These methods / classes do not exist on all versions of doctrine.
This change makes the test suite green again for 2.2 and 2.3, while
keeping the exact same tests for 2.4.
Improve the translatable documentation

- fix formatting issues
- add translatable example

test different versions of doctrine
bump branch-alias version
add missing subscriber for the tree trait

library different for the annotation driver users.
continue to map the id, for BC's sake.
warn about the deprecated id mapping
