Add string to validation

Add to axios defaults instead of overwriting them

This change ensures the default "Accept" header specified by axios is retained.

Sorting gitignore file

Make app name configurable in environment file

DRY some npm scripts

`dev` and `prod` are just aliases, so this allows to just defer them to their counterparts.

`watch-poll` just adds one extra argument so the special option `--` allows to pass it to the `watch` script.

NPM scripts should support Windows

Provide consistency with NPM scripts

Add vagrant virtual machine directory to git ignore list.

It trips me up each time that `npm run dev` exists but `npm run prod`
does not. This serves to fix that case, as well as providing consistency
in both directions `dev`/`development` and `prod`/`production`.

Added changelog

Composer -o

Composer allows us to optimize the autoloader using the --optimize flag or shortly -o.

Require laravel-mix v0.*

Possible URL fix?

The .js files should be vendored too

Some projects can present JS as the primary language, even clearly being a Laravel/PHP project. With this, that problem can be avoided.

unindex token

Mailtrap now reference smtp. for their host value.

Adds unix_socket to config/database.php for consistency

For the mysql driver only (as this only applies to mysql) add the "socket" configuration parameter and corresponding environment variable.
