Renaming the framework to prevent naming conflicts

[iAlirezaKML]

When you import this beside other libraries (Vapor for example) there will be some conflicts in type names, such as Router. In order to resolve that, you should use the module name: TelegramBot.Router but the problem is the framework TelegramBot has a class named TelegramBot so another conflict occurs.
