8615: Cluster startup and property setting enhancements
8657: Fixed shutdown procedure for JGroups
8676: Enable system property overriding of more JGroups TCP stack properties
- ${alfresco.tcp.start_port:7800}
- ${alfresco.tcp.port_range:3}
8678: More logging of cluster view changes and channel factory config during startup
12667: Merged V2.1-A to DEV/LIVECYCLE-3.1
9188: Index recovery job only calls through if property 'alfresco.cluster.name' has been set
9197: Fixed unit test after bean property name change
12793: Merged V2.1-A to DEV/LIVECYCLE-3.1
7765: Requested mimetypes
8526: Updated Mimetypes
8610: Mimetype changes
Many branding and other non-core changes were omitted

- Property 'hibernate.dialect' is set on the System
- iBatis loading (activities) checks for 'hibernate.dialect'
- SchemaBootstrap checks for 'hibernate.dialect'
12854: Merged V2.1-A to DEV/LIVECYCLE-3.1
8681: Fixed mimetype 'application/photoshop'
12856: Merged V2.1-A to DEV/LIVECYCLE-3.1
