Frontend does not resolve relative backend links

Cause: util/backend.js

---

Providing a relative path for REACT_APP_BACKEND_URL does not work. Embarrassing, but whatever.
Currently, a url such as: http://ip:port/ must be provided.

Rewriting the URL code will fix this.

Affected Components:

• org.m_flak.myblog.server.routes.PostsRoute
• posts.js
• monthlist.js

---

Description:

It seems that successive requests to the backend's PostsRoute at /posts will occasionally result in an empty response, but this does not always happen!

I'm not sure why this is happening, and it is extremely frustrating.

This bug causes some or all of the frontend components to fail. We'll either see the posts and an empty post-by-month list or vice versa. HOWEVER, sometimes everything works as it should.

Workaround:

Refreshing the heck out of the home page until things show up. This is unacceptable! 😠

Implement database connection pooling. (See #1)

#1 was caused by no connection pool for the database connection.

Connection pooling must be implemented to allow the backend to actually work properly.

Because currently, multiple connections all at once will result in undesirable behavior, like on the Home Page. Posts and the Post List pages work fine.

Frontend deployment to a subdirectory.

---

The frontend react app is limited in the way it can be deployed. Deploying the react app in a subdirectory doesn't work because of react-router.

Currently, the front can be deployed in a server's root, ex: http://whatever.com/.

The code shall be first examined, and if no fix can be made, I'll just dockerize the frontend. 😄

I, personally, must deploy my blog in a subdirectory on my production server, but if you don't, everything should work just fine.
