Change Stomp message id key from 'hq-message-id' to 'hqMessageId' and Fix ClassCastException on stomp 'connection-ttl'

• hq-message-id is not a valid name for selector
• javax.jms.InvalidSelectorException: Invalid filter: hq-message-id='STOMP19327352839' Encountered "- message - id = \'STOMP19327352839\'" at line 1, column 3.
• The dash character is invalid.
• here is the spec of the message selector:
  "3.8.1.1 Message Selector Syntax
  Identifiers:
  – An identifier is an unlimited length character sequence that must begin
  with a Java identifier start character and all following characters must be
  Java identifier part characters. An identifier start character is any
  character for which the method Character.isJavaIdentifierStart returns true.
  This includes ‘_’ and ‘$’.

setting a connection-ttl doesn't work because of the following issue:

In classe org.hornetq.core.protocol.stomp.StompProtocolManager
in method public ConnectionEntry createConnectionEntry(Acceptor acceptorUsed, Connection connection)

The following line cannot work:
Long ttl = (Long)acceptorUsed.getConfiguration().get("connection-ttl");

It raises a java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Long"
