. AVM cut/copy item clipboard support

Browse Source 
- AVM files and folders can be cut and copied to the clipboard
 - AVM files and folders can be pasted (copied or moved) around a sandbox
 - The usual "Copy of …" filename logic applies
 - Cut and Copy actions now appear for AVM nodes (as appropriate for user permissions)
 - Refactored logic for cut/copy into specific clipboard item classes - WorkspaceClipboardItem and AVMClipboardItem
. Fixed unreported issue where the DownloadContentServlet was unable to open content for AVM paths containing a space character
. Pager control border style alignment improvement
