Removed dangling pubdate attributes

The <time> attribute "pubdate" appears to no longer be part of the HTML5 spec, so remove them (they weren't being used anyways)
Added max-width to select elements in widgets to prevent it overflowing. This intends to fix a common issue - the dropdown in the category widget overflows when a blog has a long category name
Theme Customizer > Theme Options

* Removes sample theme options
* Adds Theme Customizer enhancement (actually working!)

Goal: Emphasize the use of the Customizer versus out of style Theme
Options.

show space using &nbsp; instead of actual space, as Github trims it in markdown rendering

Deals with Issue #123
add &nbsp; in replacement text too

_s: Add additional Post Formats into functions.php, to be in line with WordPress.com's Instapost posting experience.
Add a space to let it shine.

Remove generic Theme Options page in favor of the Customizer.

Customizer support is activated by default and comes with a working sample implementation. For more information about the Customizer and how to leverage it's API please see http://ottopress.com/tag/customizer/
