Change network retrieval method names

From e.g. `network1` to `network_1` for consistency with other parameters.
Change network config parameter names

For consistency, from `network1` to `network_1`.

Doing this I also noticed one of the testing config parameters was 1 instead of 2, but this is not tested, only the launcher config is fully tested so it hadn't come up before. Either use this config in a test or remove it, is a task for another day.
Bump version

This version is required to change the parameter names for consistency.
