Use puppetlabs provided precise box

The puppetlabs box has an up to date version of puppet and facter
installed.
Add options to puppet run

I find it quite useful to get the full reports and summaries out of
puppet whenever running vagrant provision. In my experience also makes
things a little less magic.
Remove `--debug` from Puppet

Puppet's debug output is quite chatty and can easily obscure the detail of
what has or hasn't changed in a given run. So I think it should be disabled
by default.

Also moved the option within the block to match style with the other
settings.
Merge branch 'vagrantfile-suggestions'
