Added a "New" Button which flushes the sheet by reloading the page.
* Added Arrow Key navigation around the sheet, whole row selection.
* Scrapped the invisible text input insertions for contenteditable cells
* Set a document name (like Google Docs)
Moved the title over a bit.
Added click-drag selection.
Fixed a tiny CSS bug that revealed some dialogue if the user reached below the table.
Added some images for use with the JS Context menu Library.
Removed the Table Default Header.  No longer needed.
* Rewrote the Row and Column adders.  These still need work, but it's something.
* Integrated Tabular.js!
* Implemented a simple uploader. Restricted to very small files (because of shitty memory handling on row/column additions)
* Integrated JQ Context Menu
* Moved some Javascripts around in an attempt to figure out why YepNope is failing to run some of its callbacks.
