增加了自动创建插件工程的Python脚本

Matthewl

　　为了避免手工创建新的插件工程，同时也是学习python，今天用了6个小时边学边试，终于编写完了。
　　学习到的新知识有:
　　1、正则表达式一次替换多种子串   
2、遍历创建目录     
3、回调函数     
4、路径模块     
5、字典的一些用法     
6、主函数、编写习惯、递进开发方式
#!/usr/bin/env python
"""
Function:   Create a plugin project based on Win32DllTempl or MFCExtTempl.
This script has been tested with ActivePython 2.7.
Usage:      makeplugin.py projname pkgname basetype
projname: name of the new project.
pkgname: package name of the new project, the default value
is 'pkg_Example'.
basetype: 'mfc', 'win32', 'view' or project name in pkg_Example,
the default value is 'win32'.
Creator:    ooyg
Date:       2011.10.9
ChangeList:
1. Implemented the function: multireplace, copyfiles, makeproj
2. Add 'view' for the param of 'basetype'.
Skip project files while copying files in pkg_Example. [2011/10/10]
