Update to gradle plugin 0.7.+
Add more host URLs
Hard code a LOGTAG in order to get rid of the 'ambiguous method call' errors on Android Studio
Use latest build tools
Update hard-coded user-agents used for forcing web modes (phone vs desktop)

Make sure to check the Android version and use the old User-Agent for devices before Android 4.4, and the new User-Agent for devices on 4.4.+, this will assure better compatibility since Android 4.4 uses Chrome's engine for the WebViews
Mobile site URL: switch back to m.facebook.com
Always load the mobile site on all Android devices unless we change the behaviour in the preferences
Increment minSdkVersion to 15
Use destroyWebView() method
Add ability to set a proxy.

If Orbot is installed, a request to start its connection will be made if the proxy is enabled and Orbot is not connected.
Update to version 1.3. Include proxy support
Set minSDK tp 14, it runs fine on Android 4.0
