Integrate the library of tools into the main LBRY code

[belikor]

These tools were developed to make lbrynet simpler to use with many files, particularly to download many claims from multiple channels, and thus help with seeding them.

It would be ideal to integrate them into the lbrynet program itself so they can be used by expert users, and by the LBRY Desktop application to manage many claims in a graphical way.
