DataManager: add DefaultScriptReader

[salix5]

single mode will read the wrong script

In single
1234.lua

In expansions/abc.zip
single/1234.lua

choose 1234.lua in listbox
The single mode will read the file in expansions/abc.zip.
如果存在以上檔名
在單人模式選擇1234.lua
將會讀取expansions/abc.zip內部的檔案
而不是實體目錄./single的檔案

gameConf.prefer_expansion_script does not work

In expansions/abc.zip
script/constant.lua

set gameConf.prefer_expansion_script to 0
It will still read the file in expansions/abc.zip.
即使gameConf.prefer_expansion_script設為0
仍然會優先讀取expansions/abc.zip內部的constant.lua

Reason:

ygopro/gframe/game.cpp

Line 1162 in 298b43a

dataManager.FileSystem->addFileArchive(fpath, true, false, EFAT_ZIP);

In dataManager.FileSystem, ./script/constant.lua refers to the file in zip.
ScriptReader uses dataManager.FileSystem to read the script, so it will always read the file in zip.

如果使用dataManager.FileSystem讀取
constant.lua會被加入./script取代原本的檔案
ScriptReader使用dataManager.FileSystem
因此不管選項是on/off都會讀到zip內部的constant.lua

nested directive

In expansions/abc.zip
expansions/script/constant.lua

set gameConf.prefer_expansion_script to 1
It will read the file in expansions/abc.zip.
如果gameConf.prefer_expansion_script設為1
ScriptReader將會讀取zip內部的expansions/script/constant.lua

solution

DefaultScriptReader
It will read the script by C function fread, and it will not read from zip file.
使用fread，只讀取實體目錄而不包含zip

Single mode script
It will search from ./single
只在./single搜尋

Card script
It will search from the following path
dataManager.FileSystem (including files in zip)
./script
./expansions/script
從以上路徑搜尋

A merge solution to server branch is needed for this PR https://github.com/mycard/ygopro/tree/server

Note: the server behavior differs, always reading specials first, and then expansions/script, and at last script
