Pagination fix

Adds support for Pagination and upgrades Bootstrap to latest version.
As your css is pulled in after the bootstrap css, if you use the same selector as in bootstrap, yours will overwrite the original.

Or you can use a higher specificity selector. E.g. if bootstrap is using
````
.thumbnails li {
    magin: 10px;
}
````
then using
````
.thumbnails li.myclass {
    margin: 0;
}
````
is more specific and should overwrite the original.
