When end-of-line is represented within a file as "\r\n",

Add a header that tells Internet Explorer (all versions) to use the best available standards support. This ensures that IE doesn't go into quirks mode because it has been blacklisted by too many users pressing the incompatible button. It also tells IE to use the ChromeFrame renderer, if the user has installed the plugin.

This guarantees that the best available standards support will be used on the client.

adds test coverage for edge-cases of Array.wrap, and better documentation for how it differs from Kernel#Array

application generation: --skip-testunit and --skip-activerecord renamed to --skip-test-unit and --skip-active-record respectively

Reason is their proper spellings are "Test::Unit" and "Active Record".
Option names and descriptions have been revised, as well as some method
names and minor details here and there.
