Fixed resize and multi-write jqplot bugs

1. The bar graph was not resizing with the layout when the window changed sizes, and instead was getting its width only when it was loaded.
   Modified the code to replot the graph when the window size changes so that it keeps shape.
2. The plot was plotting a new image over the old one. Changed by keeping a global reference to the plot and destroying the old plot before creating a new one.
3. Removed a trace that was used for debugging views.py.
CSS added

1. CSS added to make site more put together.
