* librejserver: a server program serving librejs compliance info

*WIP - it does not work yet*.

The program should return librejs report for a given page.  It should
return a JSON for a given url:

http://localhost:5678/https://fsf.org

This should return a JSON report of the compliance of https://fsf.org.

A more advanced version of this program should take user input url
(url to a webpage, not a javascript file), run librejs compliance, and
return the report to user.  If the user is ok for the report to be
shared, it will also be added to a database.  The server can then
serve a filtered / sorted list of urls by compliance, popularity etc.
This can help users discover sites that are librejs-compliant.

An even more advanced version of this program should list reasons for
non-compliance of free javascript, and librejs devs can use this data
and statistics to determine how to update the compliance check to
cover more free javascript.  A more advanced librejs can download the
database, and add javascript to whitelist depending on some threshold
from the data.

Problem:

1. This is an SaaSS
2. Without moderation or approval, user will submit nonfree javascript
