Optimized script
Update README.md

Bootstrap 3 was separated from Twitter - Bootstrap is no longer a Twitter project.  Removed references to "Twitter"
Docs: Changed reference to 'Twitter Bootstrap' to just 'Bootstrap'
Sticky table header no longer has a hidden tbody.
Created an update function which sets up rows (only new rows) and adjusts the sticky table header. Rows can only be setup once now.

Renamed setupHdrCells() to setupTableHeader()
Renamed setupStandardCells() to setupBodyRows()
Removed jshint from build task
