GDScript: 2shady4u GODOT SQLite, update_rows workaround

func update_values(table : String, criteria : Dictionary, values_to_change : Dictionary):
#   This function translates the inputs that are more convenient to provide into the ones that work with the plugin's update_rows method.
#   EXAMPLE ORIGINAL SYNTAX: DB.db.update_rows("'Home Town'", "\"Name of Town\"=\"Maybe Nowhere\" and \"Town ID\"=1", {"'Name of Town'":"Everything"})
#   table:              would need ' ' around table names with spaces in them
#   criteria:           would need \" \" around column names with spaces in them
#                       would need \" \" around cell data strings with spaces in them
#                   ALSO: "and" has to be between each criterium
#   values_to_change:   would need ' ' around column names with spaces in them
#                       does not actually need anything extra around values if there are spaces in them
#   EXAMPLE NEW SYNTAX: DB.update_values("Home Town", {"Name of Town" : "Maybe Nowhere", "Town ID" : 1}, {"Name of Town" : "Everything"})
