HTML5 the blank default project

Made index and default template HTML5 valid
Removed setting of HTML5 in Boot, as that's now the default.
Fixed copyright footer for 2014
Switched to data-lift and data-lift-content-id (from class)
Weird rendering on Chrome, fixed by changing the content span from 17 to 16 (random)
Sorry. Lots of white space change.
Found a couple more places to go from class to data-lift
Merge pull request #5 from d6y/master
