- Added to ImGui Context Proxy a name that is mapped to ini file set in ImGui context. - ImGui Context Manager generates unique context names from world type and context index. - Refactored ImGui Context Manager to have a cleaner separation between editor and non-editor bits. - Fixed context update rules in ImGui Context Manager. - Changed widgets management in ImGui Module Manager to allow automatic garbage collection after viewports are closed and manual removal when module is shutting down. - ImGui Widgets are in full control of communication with context proxies. - Added basic world context utilities. - Refactored world context index utilities and replaced ambiguous 'default context index' with 'editor' and 'game' ones.
