Preview crashes when the theme sanitizes a missing page_title.
Adds a meta viewport so the layout would act nicely to mobile devices.

This is not making Publify a real mobile friendly app, but at least it makes it useable on iPhone / Android phones which is a first step.
Fixes hcard on statuses links.
Adds some UI to fill in Twitter credential.

I need to code the whole user path here, but I first want something I can use:

* Proper link to create the application on Twitter from the settings/write and status/new
* A good setup text to explain what to do
* The good "add Twitter" link to get the oauth credentials

To be honnest, this is not really on the top of my TODO :-)
Adds an option to use a custom domain for URL shortening

You may want to pick up a significant domain name for your blog (like my-shiny-weblog.com), but use a different domain for URL shortening, like shi.ny.

Note: when they open the .ny TLD, I want the knightswhosay.ny domain.
