Much cleanup and organization

Added sudo to all the handlers (seems appropriate)
Added optional PHP error reporting parameters
Removed postfix and reboot tasks from local server init (postfix is unnecessary and reboot broke the directory mapping)
Removed VBoxGuestAdditions symlink task from system_update (it was broken and [hopefully] unnecessary)
Moved PHP params to fpm_pool config file; better localization
Added optional LARAVEL_ENV var to fpm_pool
Moved upload directory to be under /tmp because...duh.
Reduced memory in Vagrantfile to 512mb
Added timesync threshold to keep vagrant box clock in sync
Added local site setup task to Vagrantfile
Merge branch 'master' of github.com:bbatsche/vagrant-lamp
