Implement pagination for the license review tool

[radeusgd]

Currently the generated webpage report is enormous and takes a long time to load even on more powerful machines.

We should:

• restructure how the report is generated to move data contents into separate files that can be read on demand,
• implement pagination so that only a set of dependencies is displayed at one given moment,
• sort the license report so that packages with most problems come at the top and ones without problems are at the bottom.
