Merge pull request #7 from cdepillabout/fix-formatting

Fixed whitespace.
Merge pull request #8 from cdepillabout/add-dep-on-wget

Added a dependency on maestrodev/wget.
Remove changes that aren't made every time.

Everytime the play module was run, the Exec['change ownership of play
installation'] and Exec['unzip-play-framework'] would get run.  Checks
have been added to stop them from getting run every time.

Also the notice() was taken out. The puppet style guide doesn't have
anything specifically about notices, but most of the modules on puppet
forge don't use notices/notifies.
