Added a pretty_print option to the log class

It isn't useful to log arrays if the result is 'Array'.

I noticed that I often use `Log::info(print_r($array, true));` and I'am probably not alone, so why not add this as a feature to the framework?
fixed white-on-white profiler text

Update laravel/documentation/views/html.md

The second parameter of HTML::style have to be an array, not a string.
Respect LARAVEL_ENV variable

Laravel **should** respect `LARAVEL_ENV` variable when running through CLI
Update application/language/nl/validation.php

The use of 'Het' is not always correct, sometimes it should be 'De', so the sentence would look weird. Probably better to remove it.

Also, the 'exists' string stated it already exists, but should state it doesn't exist! Very important difference ;)

Also changed the formatting errors of email/url to be more specific.
