Add debug task that doesn't minify.
Move popbox and tinyscrollbar to vendor/
Rearranged grunt.js to make more sense.
Include vendor js files in grunt compilation.
Move sticigui.css to lib/ since it's actually histogram-specific
Fix typo in README.md.
Fix minor typo in HistHiLite.css
Use grunt for CSS files as well.
Updated README to reflect the fact that popbox and tinyscrollbar are now
included in sticigui.js/css.
Remove popbox/tinyscrollbar dependencies from demos since they are now
bundled with sticigui.js/css.
Merge branch 'master' into gh-pages
