Loaded in new CSS, JS, glyphicons, added in IE Edge, testing this commit.
Added in html5shiv manually. IE6-7 no longer supported. Couldn't find a good CDN for this, google usage suggests downlaoding it. 'printshiv' This is for printed elements for IE 8.
Added in respond.min.js, removed old html5shiv as using the cdn that getbootstrap.com uses should work. Response.min.js doesn't work from CDN.
Possibly completed everything, actually.
Fixed sticky footer.
Added some custom Jekyll styling, because.
Removed local respond.js given that CDN does work, just not from file://
Created a Bootstrap-3 theme, readded the twitter theme, made bootstrap-3 default.
Remove empty quotes when category is empty.

When category = ""

Should print "category: " to file, current behaviour prints "category:
\"\"".

Latter creates an actual category, with a blank title. All posts created
since this update, without a category explicitly written in `rake`
command, or post directly edited, will belong to this category.
Simpler logic to category patch

Replace single line with cleaner, more readable Ruby.
