[Mobile] Home page image caching

[AlicanM]

If a post item is returned to the view in the home page, its images are requested again. I will change the structure so that for each post its image will requested only once.

I implemented a new class PostAnImages

• This class stores the image and the avatar widget of the post
• So when creating new FeedContainer, those datas are used instead of requesting
• commit

Created the PR, since this implementation solves the issue. Ready for review @canatakan
