Reorganized and updated ruby management scripts

- Ruby version has been updated to 2.0.0

- Directory structure has been reorganized so that scripts are organized
  in a sensible way depending on their particular functions

- bootstrap.rb defines global functions and rake-specific
  configurations. The configuration includes path data, editor, post
  extension, database name and location as well as any directories to
  NOT deploy in the compiled output. In addition, bootstrap.rb loads the
  Jekyll configuration file so that the data defined in _config.yml can
  be used by rake tasks

- Rakefile loads the bootstrap file and invokes a rake tasks import as
  well as rake support file imports

- _config.yml now holds an identifier for the current environment type.
  This will allow rake tasks to perform different operations based on
  the current environment type.

- All rake support files now use configuration data loaded or defined in
  bootstrap.rb
