我稍微修改的 telegram 版本（Fork from DrKLO/Telegram）：
- 修改 超过1条未读消息时候，通知（包括浮动通知）的消息不再只显示 x new messages，而是直接在通知中显示消息内容。
- 增加 类似微信的习惯，打开表情栏的时候，点击上面的聊天区域，自动关闭表情栏。
- 修改 包名，可以和原版同时安装同时存在（虽然没有必要。telegram 会自动同步所有内容）
- 修改 提及(@)列表的高度为更合适的高度
- 修改 群聊输入栏右边固定一个
@按钮，如果有/按钮，则替换之
基于官方 v3.1.3 版本的分支开发。因为官方限制，所以我们开发的 telegram 不能叫做 telegram（Please don't use the word Telegram in the title of your app.）。
telegram 需要翻墙，初次启动它会同步下来所有聊天记录，所以这时候有可能比较卡，之后就好了。

其中 Teleet 是大众版，Tel4Drakeet 是我个人版，二者几乎完全没有区别，除了 App 名字不一样。

Beware of using the dev branch and uploading it to any markets, in many cases it not will work as expected.
First of all, take a look at src/main/java/org/telegram/messenger/BuildVars.java and fill it with correct values. Import the root folder into your IDE (tested on Android Studio), then run project.
