Allows seeding layouts

[merschformann]

Description

Allows specifying a seed in the layout configuration. This seed is used for randomly positioning pods, bots, etc. Previously, stored layouts should be fully compatible as a missing seed acts as a 0 seed value, which was the previous fixed default.

The seed can be configured in the UI via Instances > Instance layout > Seed and in the XML:

<LayoutConfiguration>
  ...
  <Seed>0</Seed>
  ...
</LayoutConfiguration>

⚠️ Note: This seed only affects the layout being generated. There is already a seed available to change the stream of random events for the running simulation. Find it in the setting configuration.
