[WIP] TimeTrack laravel Port

This is a work in progress for the porting to laravel of the project. The very basic functionality is ported (pages, navigation etc), other things are missing. If you want to take a look:

Clone my repo and checkout this branch:

    git clone https://github.com/desyncr/timeTrack.git
    git checkout laravel-port

Then install vendors and run the local env:

    composer install
    php artisan serve

You can go to `localhost:8000/login` and log in with user name `dc` and password `password`. To create new users go to `localhost:8000/signup`.

If something doesn't work as expected report it here. If you have any question and don't know how to run the application you should also use this PR to ask for help.

- [x] various pages: login, signup, home, etc
- [x] users creation and login process
- [ ] fix missing styles for session alerts, form errors, etc
