Migrate player list gui to scenario (#421)

* Migrate player list gui to scenario

Move modules/gui/player-list into exp_scenario/gui/player_list using the
new exp_gui element API, matching the other scenario guis.

- Store the selected player and action on the container's player data
  instead of a datastore, folding the datastore on_update reactivity
  into explicit setter functions
- Switch the actions config to injected accessor functions and the
  exp-gui_player-list locale namespace
- Add the locale section, register in control.lua, and disable the
  legacy module in the file loader

* Align names and call patterns to best practice

Apply the conventions from the rocket info gui review to the player list,
and remove the now migrated legacy module.

- Move row building onto the table def as calculate_row_data, and refresh
  via refresh_player which computes the row data once per player
- Store the selection on the container with private/public accessor
  methods instead of poking element data directly
- Store the selected player as a LuaPlayer rather than a string and update
  the actions config to match
- Use :style{} on the player table and make the action and reason bars
  their own element definitions
- Delete the migrated legacy gui and its file loader entry

* Address player list review feedback

- Rename the player table element data class to element_data
- Remove the redundant offline selection clear; on_player_left_game
  already clears any selection pointing at a player who disconnects
- Move the action bar and reason bar visibility into their own refresh
  methods so refresh_player just delegates to them
