Graveio needs a couple of packages to be installed.

Use chef-rvm to install Ruby 1.9.3

o Add recipe "rvm::vagrant" and "rvm::system" for Ruby 1.9.3
o Add ppa for node.js so we can run with node v0.10.21
o Add "chef-rvm" as submodule
Run "git submodule update" in "before_install".

o git submodules need initialisation before Travis Run
Switch submodule "cookbooks/apt" to use https URL.
Revert "Run "git submodule update".

Travis already takes care of git submodule initialisation,
therfore we revert the commit.
The problem was caused due to the fact that cloning the git
upstream repository with git:// instead of using https://
fails.

This reverts commit 253dcba6bfd11cc7884158c94911948cd65b38af.

How to boostrap the Virtual Development Machine.

o Add prerequisites of the Virtual Development Machine
o Explain the bootstrap process
o Setting up graveio on Virtual Machine
o Add Vagrant-specific TODOs
Get rid of desprecation warnings

Running "rake db:create && rake db:migrate" leads to
a deprecation warning for config option `config.whiny_nils`
and `active_record.auto_explain_threshold_in_seconds`
due to the fact that newer Rails and Ruby versions
dropped these options.

As graveio switch to Rails 4 and we are running
with Ruby >= 1.9.3 we can safely remove them.
