Added Splash Screen

[FawadMahmood]

to configure splash screen update splashscreen.psd

run following commands:
yarn patch-splash-android (it will give you a prompt but don't overwrite styles)
yarn patch-splash-ios (use project name "RNNStarter" and let it override everything)

PS: Do update the readme file accordingly.

FOR Android:-
Generate Android assets using RN-Toolbox

Run the following command:

$ yo rn-toolbox:assets --splash splashscreen.psd --android
You will ask these questions:

Project name: Type your project name or just enter if the suggest one is correct.
Overwrite styles.xml: Type “n” (no) then enter.
Overwrite colors.xml : Type “y” (yes) then enter (only ask if colors.xml already exists)
The script will add/modify the following:

Add drawable assets with launch_screen.png name
Add a drawable name launch_screen_bitmap.xml . We will use this file as the background image of the Splash Screen layout
Add a splashBackground item in colors.xml the color code will be the primary input color
Note: You have to discard any changes of styles.xml file if you accident overwrite it when running the script.

FOR IOS:-
Generate Android assets using RN-Toolbox (Optional)

Run the following command:

$ yo rn-toolbox:assets --splash splashscreen.psd --ios
You will ask these questions:

Project name: Type your project name or just enter if the suggest one is correct
Overwrite project.pbxproj: Type “y” (yes) then press enter
Overwrite Info.plist: Type “y” (yes) then press enter
This will add/modify the following:

Create a new LaunchImage.launchimage file that contains parsed assets
Remove UILaunchStoryboardName key and its value from Info.plist
Add ASSETCATALOG_COMPILER_LAUNCHIMAGE_NAME config for both Debug and Release build settings
This will do all the works. You don’t have to do anything else.
