Support a root-level "info" key which describes the over-all program/package

being installed (free-form text, up to 79 chars for pretty-print).
Remove the "requires_service" key, replaced with:
Add ability to install/update services.
Add ability to add/update sections in .ini files with eval()'d key values.
This allows the json-service dependant scripts to (mostly) be installable
under all scenarios. tw2.js is still an exception.
