[2022-01-04] Release

This is the initial release of Elurair, which is a merge of RO Patcher Lite, for the patching part, and ROCred, for the user interface. Internally Elurair is considered a fork of ROCred, that's why it starts with version 2 and 10th anniversary. Existing ROCred configuration should work, except that patcher configuration has to be added. Documentation is provided in form of a annotated sample configuration and skin. For more details see also the doc/ directory. For now GPF and RGZ files are supported; RAR, THOR and ZIP are considered and are left for community-feedback.
