Refactor: rename class name and UI prompts

[KangLin]

Issue

• The current client connection framework works very well. However, the naming is not friendly to the non-connection framework, and its function is not immediately clear.
• The server framework is similar to the connector framework and can be merged.
• The UI prompts are not friendly to non-connected functions. eg: Menu->Remote->Connect->Tool: Wake on lan

Solution

• Rename UI prompts

Current name	New name	Function
Remote	Operate	Menu
Remote->Connect	Operate->Start	Menu or tool bar
Remote->Disconnect	Operate->Stop	Menu or tool bar

• Rename the class name of interface.

Current name	New name	Function
CClient	CManager	Managing plugins
CPluginClient	CPlugin
CConnecter	COperate	Operations in the main thread (UI thread)
CConnect	CBackend	Specific implementation(background thread)

• Add TYPE type() member function in the CPluginClient

enum TYPE{
 Client,
 Server,
 Tool
}

• Remove RabbitRemoteControlServiceConfigure application, merge it to RabbitRemoteControl.

Please review and make sure that the new name or optional name is more suitable for this function?

• Rename UI prompts is finished

Current name	New name	Function

Remote->Connect	Operate->Start	Menu or tool bar
Remote->Disconnect	Operate->Stop	Menu or tool bar

Operate->Start by current classification or by type？

Operate->Start->Client
Operate->Start->Server
Operate->Start->Tools
