make test xml files valid, adapt medium lorry model to match original FWD model (so testcase succeeds)

updating testcases and writng reports after migrating to new schema version. removing no longer needed files

corrections in schema: allow only specific powertain architectures, depending on xEV configuration, bugfixes, more sample XML files

renaming schema version to 2.10, adding first draft of schema for vehicles, sample xml files for components, and heavy lorries

in case eta for REESS correction cannot be calculated (no charge/discharge situations) set correctable energy to 0
