Bug fixes in version 1.7.8 

Admin Login Error:

The variable name mismatch in game/prolog/prolog_school_paa_chat_talk.rpy has been corrected by changing prolog_school_paa_chat_admin_login_attempt to prolog_school_paa_chat_admin_login_attempts.

Student ID Input Error:

The toint function in game/functions/string.rpy has been modified to handle empty strings and invalid inputs by incorporating error handling.

Save/Load System Issue:

A new config.load_failed_label setting has been added in game/options.rpy to point to a designated label.
Additionally, a new after_load_fix label has been created in game/script.rpy, which prevents rollback when loading a save. This ensures that the game does not revert to previous events. NEW saves in the prologue should actually work as expected now.
