+ added legacy ruby 1.9.3 option in the generator menu.rb
+ db connection configuration settings are now asked both for PostgreSQL
and MySQL (mysql2) in the same block, in menu.rb
+ added mysql.yml template for database configuration in lib/railsbricks/assets/database/
+ config_db function in app_generator.rb now uses the configuration options also for MySQL,
  if it was selected as the option for the database
+ added options in menu.rb to make it optional to update Rails and/or Rake/Bundle tools, to avoid damaging or unwanted updating of already
existing environments. The option is cool for new apps tough, but not to be taken carelessly for existing ones.
+ configuration assistant now suggest a proper default port for db
connection depending on the selected db type (ie: 5432 for PostgreSQL,
3306 for MySQL).
+ added the required gems to the Gemfile and the gemfile_builder for the
new features:

	* mysql2 gem is added if MySQL option has been selected in the configuration assistant

	* tzinfo-data gem is added on Windows systems as Rails 4 & RailsBricks 3 need it on this platform
+ On Windows systems, path to the "MySQL Connector for C" files will be
asked and used in the install process to build the native mysql2 gem using
DevKit
+ Added a "getting started" guide for the new MySQL support in RailsBricks

  The guide explains how to install the prerequisites (ie: mysql2 native
  gem) to have transparent MySQL support on RailsBricks

  It has been successfully tested on both Linux and Windows systems.
+ Updated the README.mysql.md file and version strings to clarify status
