patch: 
用户姓名的部分，根据issues#655。
为了修改方便
alias：
方法     之前显示            调整之后
name     firstname+lastname  login
nickname xxx                 login
realname xxx                 firstname+lastname

User model经过修改，已经完全集成了user_extensions的功能
例如
user.gender=1
user.save
user_extensions字段会自动保存
不必要每次user.user_extensions.xxx以及判断是否为空

  # fixed domain url in development. tantantan's bug
  if Rails.env.development?
    methods.map do |m|
      define_singleton_method m do; nil; end if m.to_s =~ /([a-zA-Z]+_domain)$/
    end
  end
  程序部分链接中制定了subdomain参数，使链接在二级域名中来回跳转。
  为了开发方便，使之功能在development模式下失效。

0606：新坑
user_scores表结构有问题，需要运行
bundle exec rake db:migrate:down VERSION=20140410021724
bundle exec rake db:migrate:up VERSION=20140410021724

0708：CKEditor插件加载方法
1.把插件文件夹拷入plugins文件夹，确保文件夹名为redmine_ckeditor
2.运行 bundle install --without development test
3.运行 rake redmine:plugins:migrate RAILS_ENV=production
4.启动服务器
5.把文本格式 (Administration > Settings > General > Text formatting)改为CKEditor
6.配置CKEditor插件(Administration > Plugins > Configure)

某些情况数据库未插入插件配置值解决方案：
1 复制plugins
2 启动rails
3 运行migrate
3 打开admin配置插件（http://127.0.0.1:3000/settings/plugin/redmine_ckeditor）
4 点击“查询”(就是确定的功能)
===============================================================================
