Bug: Inheritance job cannot handle inheritance from same container

See merge request caosdb/caosdb-server!54

DOC: update README_SETUP on server-side scripting

See merge request caosdb/caosdb-server!59

Refactored sss bin dirs

See merge request caosdb/caosdb-server!57

This deprecates the server property "SERVER_SIDE_SCRIPTING_BIN_DIR"  The new server property accepts a comma or space separated list of directories.

BUG: query with parenthesis

See merge request caosdb/caosdb-server!56

Prior to this fix, query parse would throw an error when the query had a form similar to ... WITH ( (...) {AND,OR} ...). The reason were the nested pair of parenthesis in the first element of the disjunction or conjunction.

DOC: add information on how to create the keystore from cert files

See merge request caosdb/caosdb-server!53

FIX: Forcing SRID initiation also for ChecksumUpdater

See merge request caosdb/caosdb-server!50

Necessary for bug #99.

FIX: Updated remote Maven URLs.

For issue #98

Fix quotes around datetimes

# Summary

This MR will fix #39, i.e., queries with quoted datetimes and add corresponding unit tests.  It will also improve error handling for ill-formatted datetimes in queries.

# Focus

- datetime rule was removed in `CQLParser.g4` 

# Test Environment

Use `f-quotes-around-datetimes` in caosdb-pyinttests

# Summary

Introduces versioning for entities.

# Focus

Important classes/changes:

* `src/main/java/caosdb/server/entity/Version.java` - the class that represents an entity version. The XML Serialization is done by `src/main/java/caosdb/server/entity/xml/VersionXMLSerializer.java`. Parsing is not necessary as for now.
* `src/main/java/caosdb/server/resource/AbstractCaosDBServerResource.java` - In this class the requested entities are parsed from the last URI path segment. Until now, we assumed, that everything which is not an integer is a name. Therefore we had two  separate getters for requested ids and requested names. Since this assumption is not true anymore, we only have one. This results in changes in several other classes (grep for that method).
* Maybe not so easy to understand: `retrieveValidSparseEntityById` in `src/main/java/caosdb/server/jobs/Job.java`. This is a convenient method to get the entity from the container (if present) or from the database. See the code comments and please come back to me, if that is not sufficient.

If not-to-be-changed entities are in container.

# Summary

See summary of https://gitlab.com/caosdb/caosdb-webui/-/merge_requests/72

Funny side note: this MR !47 and the issue it resolves #47 have the same number  

# Focus

* The important changes are in `RetrieveFullEntity.java`, `EntityToElementStrategy.java` and `SetFieldStrategy.java`.
  * `RetrieveFullEntity.java` is responsible for the retrieval of entities and it needed additional functionality to retrieve referenced entities recursively. It does this but only if a list of `Query.Selects` is there and non-empty, because this is the case when the request is a SELECT query.
  * `EntityToElementStrategy.java` is responsible for the xml generation. It was kind of buggy and I did some refactoring there.
  * `SetFieldStrategy.java` is decides whether a property of an entity is to be included in the generated output (xml) or not. 
Additional functionality is added to cope with deeply nested references.
* Note: I also deleted the AWI stuff, because I didn't want to refactor these classes.
