Update a bit the First Steps with Titanium post

Update a bit the First Steps with Titanium post. Added a bit of code
regarding the WebView creation and difference between loading an URL or
loading your own HTML page in a WebView.

Also, upload to the repository my _drafts template so I can start
writing another drafts quicker.

Also, create first drafts of a post studying a basic videogame done with
HTML and the canvas tag.
