Skater slot, menu and throwdown fixes; MY MODS rework; lobby parties

Saved skaters (Extension/Customization, Extension/Skater)
- The selected slot, and slots before it, came up as the standard
  skater after a start or map change. The game asks for a slot's saved
  outfit once per level, and that happened before the cosmetics catalog
  could be read. The first selection now waits for the catalog (60 s at
  most), and later map changes check against the catalog already read.
- The retry from abdda77 is removed: the record it wrote to is a
  temporary on the game's stack, so it could never work.

Pause menu (Extension/UI/NativeMenu)
- ReSkate's entries stopped working after enough map changes: each
  level change took new slots in a fixed table of 1024 for the same
  buttons. A button now keeps its slot, and a full table hands out the
  slot that has gone longest unused.

Throwdowns (Extension/Throwdowns, Runtime/runtime_init.cpp)
- Multiplayer crashed when someone placed a throwdown after a map
  change. The event types are freed with the level but were cached for
  the process. They are now cleared when a level is left, checked
  before use, and looked for again in each level.

MY MODS (Launcher/gui_mods.cpp, gui.cpp)
- Search, a filter and an order; a switch per mod; a menu per row.
- Multi-select with tick boxes, Shift-click and Ctrl+A, and a bar to
  enable, disable, move, update or uninstall everything ticked.

Lobby parties (Extension/Multiplayer/Session)
- A lobby is no longer one party. Its host keeps parties the way a
  dedicated server does: invite, accept, join, leave, kick, promote,
  open and close, with "/p" party chat. The "Lobby party" switch is
  gone. Protocol version unchanged (38).

Mod merge (Engine/Vfs), follow-ups to e715b9b
- Files rewritten into the merged patch are tracked by position, so
  another mod's added assets no longer shift the lookup.
- Two mods adding different assets under one name is now noted, with
  whose copy the maps get.
- mod_merge_unshift_tests compiles with the launcher tests on.
