[Enhancement] Add sessions items to Notepad++ plugins sub-menu

[pidgeon777]

It would be nice to add currently existing sessions to the Notepad++ plugins submenu so that they can for example be recalled via shortcuts assignable through the Shortcut Mapper.

Hello,edit contextMenu.xml and add to end file

   <Item id="0"/>
    <Item PluginEntryName="Session Manager" ItemNameAs="session_name1" PluginCommandItemName="session_name1"/>
    <Item PluginEntryName="Session Manager" ItemNameAs="session_name2" PluginCommandItemName="session_name2"/>
</ScintillaContextMenu>
