多功能字幕滚动 - Project1

=begin
说明：
01 把字幕强化了，添加对话框的一些功能到里头去。
\f[字体]：更改字体
\c[颜色]：更改颜色，与默认对话框相同
\s[字体大小]：更改字体大小
\p[图片名称]：显示在picture文件夹下指定的图片
字幕：被包围的字将会变成粗体
字幕：被包围的字将会变成斜体
<left>：该行左边对齐
<center>：该行中间对齐
<right>：该行右边对齐
02 调用方法：(1) $scene = Scene_Credit.new
(2) $scene = Scene_Credit.new("文字")
(1) 为默认调用发，字幕会直接读取脚本里设定好的字幕
(2) 为更改字幕，字幕将变成设定的文字，支持\txt[TXT名称]，将会读取
Credit文件夹底下的指定TXT，TXT格式参考范例。
03 其他玩转设置参考范例。
