update vendor librairies

Hi all,

i updated the vendor libraries version, but there is a few things to note :
* I changed path of the scripts and styles folders to javascripts and stylesheets so they have the same name as in the public folder
* i did use the min versions of libraries, it's a template, if someone wants more control on these libraries he will change that for his particular project
* the full bootstap min js is now included
* i had to add an "assets" folder in vendor folder in order to add the fonts used by bootstrap

let me know if it doesn't fit your standards.

final note : i really don't know how to test that.
