Add show_menu and hide_menu ESC commands

Fixes godot-escoria/escoria-issues#48
Fix: tween was stopped_all before starting


Fix: reload locale from settings in ESCGame

Since main menu and pause menu are now loaded from ESCGame and not from escoria.gd, this must be done here.
Fix: small crash in load game

But save and load are broken at the moment...
Fix: check save and load after main menu changes


Required fixes


Fix: manage the game scene better in show and hide_menu


Enh: transition back in to the previous room if there was one


Fix a bug occurring where change_scene awaits forever for setup to end


Reworked change_scene and esc_room implementation to avoid yielding


Added a controller variable to allow new event run in events_manager


Don't empty the events queue if the running_event was interrupted


Fixed transitions and automatic transitions in change_scene

Added trace log level (for esc_compiler in particular)
Fixed various bugs in ESC scripts
Fix a bug where exit_scene happened multiple times where fast walking

Needed to clear the event queue
Fixes ready event was run because BYPASS_LAST_SCENE wrongly set


Inverted parameter "disable_automatic_transitions"

for change_scene, hide_menu, show_menu commands
Fix broken sched_event
