Remove deploy.sh

It didn't work as expected because of git's automatic line ending changing.
Fix whitespace between boxes

Changed CSS; checkbox-divs (.checkboxes) are now vertical arrays of
    checkboxes, and are listed next to each other (previously they
    were listed under each other).
Before:
    div.checkboxes { display: block; }
    input[type='checkbox'] { display: inline; }
After:
    div.checkboxes { display: inline-block; }
    input[type='checkbox'] { display: block; }

Also changed JavaScript function 'getCheckbox' to accompany this
    change.
Remove vendor prefixes from CSS

These are not really needed in the source code since
    Grunt.js already adds them.
Add HTML meta to Gruntfile, add meta description.
Add pencil and eraser tool, fix drawFromBinary

Added function getAllCheckboxes.
Fixed drawFromBinary, previously if you provided it with less than
enough bits to fill all checkboxes, it would fill all remaining
checkboxes with 1 instead of 0.
Added 3 tools, these activated by pressing a number key, and used by
hovering over checkboxes.
[1] is pencil
[2] is eraser
[3] is nothing (removes all mouseover handlers)
