Haketilo

automatically change repo url to point to api v2 endpoint

assume and use "$schema" properties in item definitions

fix loading initial data and verify it in automated tests

change store names and data keys to singular

adapt to changes in file path format

From now on we assume Hydrilla serves file contents at 'file/sha256/' instead of 'file/sha256-'.
With this commit we also stop using the "hash_key" property internally.

make Haketilo buildable again (for Mozilla)

How cool it is to throw away 5755 lines of code...

Add default repository to default settings

use default settings that only contain a demo script (the rest is available through Hydrilla)

change default repository URL

Facilitate installation of scripts from the repository

This commit includes:

• removal of page_info_server
• running of storage client in popup context
• extraction of some common CSS to a separate file
• extraction of scripts import view to a separate file...

Revamp default settings

Default settings are now provided in the same format as data exported from the
extension, incorporating them into the main program as part of the build
process. Also, modify their contents; the apparently non-functional FSF stuff
is gone, replaced with fixes for BandCamp, WorldCat, and SumOfUs.
