Large identifier capability check in Open Server

Open Server now checks to see if connected clients have the capability to support large identifiers. If clients do not support large identifiers, and request objects with names larger than 132 bytes (the pre-15.0 identifier limit for Client-Library), Open Server displays the following errror:

Identifier starting with <name> is too long. Client does not support Large Identifiers.

where name is the name of the identifier.
