Integrate Flower and Hanappe.

[makotok]

File size of Flower is bloated. Modification has become troublesome. In the next version, I consider the following things.

• While maintaining the compatibility as possible, to divide the file.
• Integrate flower-library and flower-extentions
• Integrate Flower and Hanappe.

• Added the ability of Hanappe to Flower.
• Split Flower module.
