Added package def for wget.

I was running into the same error as listed in this fork
https://github.com/schrepfler/puppet-jdk_oracle/issues/1

Followed the suggestion of adding
package { 'wget':
  ensure => present,
}

I am installing on Ubuntu 13.10.
#19 - Added wget package if not already defined.
Merge branch 'Cinderhaze-master'
