Merge branch 'master' into Bug534-NingShushuang

了对密码中特殊字符和大小写字母的包含要求检查，并将密码的最低长度限制提升到 8 位以提高用户密码的安全性。
但与该版本EnglishPal中jsonify函数起冲突。

验证码机制
在EnglishPal/app中增加了generate.py函数，该函数用于生成验证码图片以供调用，需要先运行此函数，图片将会保存在app/static/captcha中。
在main.py中注册了两个新路由，用来接收前端用户提交的刷新验证码请求和验证码匹配检查请求。
修改了app/templates/signup.html的样式表和表单，新增了两个js函数，Change()用于检测用户刷新验证码的请求并发送给后端以切换验证码图片，Check()用以检查用户输入的验证码是否与图片匹配。
