【FSL】全局哈希 - Project1

#==============================================================================
# ■ [XP/VX] 全局哈希
# [XP/VX] GlobalHash
#----------------------------------------------------------------------------
# 使用说明:
# 创建一个不受存档影响的哈希
# 用于保存游戏X周目、CG的收集状况等
# G_Hash#clear
# 清空哈希
# G_Hash#load
# 读取哈希
# G_Hash#save
# 保存哈希
# G_Hash#read(key)
# 返回key对应的val
# G_Hash#hash
# 返回整个哈希表
# G_Hash#change(key, val)
# G_Hash#change([key1, key2, ...], val)
# G_Hash#change({key1 =>val1, key2 => val2, ...})
# 修改哈希的值，若修改了@hash的值则保存
#----------------------------------------------------------------------------
# 更新作者： Tune_U
# 许可协议： FSL
# 项目版本： 1.0.1013

# - *1.0.1013* (2010-10-13) By Tune_U
# *当G_Hash#change没有修改任何值时不再save
