Rake tasks about ginatra

[lenary]

Giving the Rakefile the once over. Closed by 3be6c72

Deleted:

• submodules:init
• submodules:update
  These two were for heroku and didn't work

Modified:

• test:spec
• test:features
  These two have now been de-namespaced. They still work, but have a large
  message to tell you not to use them. Replaced with spec and features
  respectively
• test:current
  This has been moved to the features namespace. It is now features:current

Added:

• spec:long
  Runs the RSpec Test Suite with --format specdoc. This output is longer, but
  more useful.
• spec:html
  Runs the RSpec Test Suite with --format html:spec/html_spec.html. This is
  then opened in the browser. Fun over functionality.
• setup:gems
  Installs the required gems. Magic! Will probably require sudo
• setup:repo
  Adds the test repository, so that you can run the tests
• setup:test
  Installs the test gems. Magic! Will probably require sudo
• add
  Easily adds repositories to the git_dir. Use repo= to specify a git url, and
  name= to specify an optional name.

they need the once-over again, i need to update the repo:add, add a repo:update and create a few cache clearing tasks, i will also think of more later, as usual

just realised, none of this is needed as we're going to use rack-cache
