Add css changes from commits dcca1615 and 399a11b9

Both the commits contained modifications made directly to the .css.
These changes will get reverted whenever the .less file is compiled.

Install the less gem and run "lessc assets/less/style.less >
assets/css/style.css" in the root directory everytime a modification
is made and make sure those modifications are done in the less file also.

TODO: This action should be a rake task
