[CheeseBrowser] Multiple commit

Bug fixes:
	1. At 24th middle school, when android boot complete,
	the device network not get ready. At the time, system
	auto open baidu browser and open the web page, lead to
	display error web page.
	   For this problem, system listen CONNECTIVITY_CHANGE
	action, if received, wait 1 minutes, then open target
	web page.

Functions:
	1. Later, system will use internal WebView instead of
	baidu browser. So, we add the internal WebView arch.
	   related files:
	   	activity_webview.xml
		WebActivity.java
	2. System need support remote control fuction. Now, we
	add the arch. Related files:
		ControlServer.java
