First Pull request for code review - Registration, User Log in, Pagination

instead of adding hello controller/model/view in the .gitignore, you can just delete the files in both git and directory po

```sh
git rm app/controllers/hello_controller.php
git rm app/models/hello.php
git rm app/views/hello/*
```

also for the log files, you add a whole directory to gitignore :bow:

```sh
app/tmp/logs/*
```
