Automatically create the reverse relation to other sign #275

Closed ocrasborn closed 7 years ago

ocrasborn commented 7 years ago

When specifying sign B is related to sign A (the one being edited), automatically add the reverse relation for sign B.
Homonyms, synonyms, and antonyms should get the same type; hypernyms and hyponyms should get the opposite type • Upon deleting one member of the pair, also delete the other member.

Perhaps the code @ErwinKomen wrote to make the morphology links bidirectional can be reused, see #128

Done.

Note that when creating a relation, the reverse is also created, even if the reverse already exists. This is because identical relations may occur more than once. When deleting a relation, the first found reverse relation is deleted.

That should be fine: after we do some initial cleaning up, new 'doubles' should not be created anymore thanks to this new functionality. I'll keep the issue open for me to test.
