load JS at Landing page

* Loading Javascript at the loading of the Landing page. 
* The money shot call Portal.app.init() is now inline JS in home/index.jsp for all to see what kicks of the meat and potatoes instead of in one of the hundreds of included JS files.
* The shuffle of css load ordering had the benefit of clearing up the Grails admin pages, plus my nips and tucks.
* Also fixed a hover css rule on the login popup.
