Javascript libraries packaging

As part of Action Chaining, here are some tentative specfiles for the new Javascript libraries.

To test those I need Koji access and the following source files, as specified by the Source: tags:

 - http://jqueryui.com/download/#!version=1.10.4&components=1110000010000000000000000000000000&filename=jquery-ui-1.10.4.custom.zip
 - https://github.com/ivaynberg/select2/archive/3.4.5.tar.gz#/select2-3.4.5.tar.gz
 - https://github.com/t0m/select2-bootstrap-css/archive/v1.3.0.tar.gz#/select2-bootstrap-css-1.3.0.tar.gz

As this is my first attempt at Fedora packaging, comments are welcome!
