Allow comments in json

[LDAP]

Parsing failes when json contains any comments.

Error output:
"maybe a (non-standard) comment? (not recognized as one since Feature 'ALLOW_COMMENTS' not enabled for parser)"

This is expected behavior and by design of the JSON parsing library, since JSON does not specify comments (see RFC 8259). As the error suggests, the parser does however support comments.

Do you have a use case in mind where we would benefit from comments in JSON files? @LDAP

[LDAP]

Yes.
I was about to write additional information into the time sheet e.g. why certain meetings took longer than usual. Such information does not fit into the "Activity" field.

[larsk21]

I see. Since comments in JSON are always a little messy, would it help to add an optional comment field to the JSON definition that is ignored by the parser?

[LDAP]

This would be a suitable alternative

@gstuer Do you have any preferences here?

[gstuer]

As @larsk21 stated correctly, JSON does not specify and consequently does not support comments, even if they are available within our specific parser. Therefore, I would prefer @larsk21 solution concerning the optional comment field. We could use this in the near future within the GUI #20.
