Add a dedicated ShareHostDlg with a "Use Shine protocol" checkbox (default
checked) so the operator can choose Shine (0) or HELL (1) when sharing or
transferring a host. The chosen protocol is appended to the wire payload as a
trailing colon field: "IP:PORT:0/1" for share and "IP:PORT:days:0/1" for
transfer.
The client parses the trailing field from COMMAND_SHARE and
COMMAND_ASSIGN_MASTER, applies it to new connections, and persists it so
auto-share/auto-transfer on restart keeps the same protocol. Old clients
ignore the extra field, and old/missing payloads fall back to -1 (baked-in
HELL), preserving compatibility with existing servers and share_list entries.

Record the client's active-window history (start time, window title, and
dwell duration), newest first, skipping dwellings under 5 seconds and
breaking the timing on idle, capped at 500 entries. Add an "Activity
History" item inside the host's Client Management submenu that requests
the snapshot over the main connection and shows it in a new dialog. The
dialog rebuilds its edit control as a Unicode window so UTF-8 titles
render correctly instead of degrading to "?" through the MBCS ANSI
boundary. The menu item and dialog title go through _TR and are
localized in en_US and zh_TW.
