a little touch up and fixing of loading in comments in the posts.js file

some small changes

fixed some styling on the posts side, specifically the post and posts css which were very messy.

It now works to load in new components fetching a certain number of posts from the backend at a time

and fetching posts that matches a word.

created routes for
deleting posts
fetching profile posts
saving profile information to posts
loading animation
ect.

when logging in the user is now redirected to their profile page.

This is done through storing the user inside a token which is verified when refreshing the profile page
