improvement of flower.openWindow

[makotok]

flower.openWindow, it is necessary to explicitly specify the size.
If many of the mobile environment, I'm just a little trouble handling this.

local screenWidth = MOAIEnvironment.horizontalResolution or 320
local screenHeight = MOAIEnvironment.verticalResolution or 480

flower = require "flower"
flower.openWindow("Flower samples", screenWidth, screenHeight)
flower.openScene("main_scene")

Change as follows.

• If you do not specify a size, open the window with the optimal size for your environment.
• If you specify a size, I open the window with the specified size.

flower = require "flower"
flower.openWindow("Flower samples")
flower.openScene("main_scene")
