xenadmin/XenAdmin/Commands/MoveVirtualDiskCommand.cs
Konstantina Chremmou eb3fbe2ac8 Corrections and refactoring on VDI move/migrate:
- Allow move of multiple VDIs
- CA-187659: show better messages when batching move/migration of multiple VDIs.
- Show different tooltips for single vs. multiple VDI move/migration/deletion.
- Refactored the MoveDiskDdialog. Removed the inherited class VDIMigrateDialog and
the batching manager as it was not very different from its parent, it was registering
the events twice, and was batching migration of even single VDIs.
- Tidied up the Move- and MigrateVirtualDisk commands so they're easier to compare.
