(Theme) Initial addition of the YinYang theme

Using the instructions here:
https://github.com/qingwang/octopress-theme-yinyang
Added the YinYang theme.  However, this doesn't seem to work properly.  The rake preview command results in the following:

Liquid Exception: Included file '_includes/custom/archive.html' not found in blog/archives/index.html

Investigation required.
(Theme) Correcting rake preview for YinYang

In order to fix the rake preview of the YinYang theme, had to add a missing archive.html file which is located at:

```source\_includes\custom\archive.html```

For the time being, used the version of the file from here:

https://github.com/qingwang/qingwang.github.com/blob/source/source/_includes/custom/archive.html
(Theme) Fixing YinYang Theme

 - In order to get the YinYang theme to do anything, had to modify the header.html to remove the commented section
 - Removed duplicate header information in custom/header.html
 - Deleted temporary test blog post
 - Added additional social media accounts
Initial Import of Blog Posts

After using the exitwp utility:

https://github.com/thomasf/exitwp

 - Did an initial import of all the blog posts that I have done.  Right now, the site is completely broken.
 - None of the images are going to work until I include them in the assets folder, and a lot of blog posts are going to need to care and attention to make them right, but for now at least, the original content of the blog is there.
 - Tweaked the layout and navigation to make the site look a little better
