[Infra UI] Selectively sync state to the url

[weltenwort]

In order to facilitate linking to and sharing of of UI state, parts of the local state should be synchronized to the url. These include:

• waffle map time state
• waffle map filter state
• waffle map entity and grouping state
• waffle map display settings
• log position state
• log filter state
• log display settings

These should be written to the url on change and read when entering the respective page. Constant reading from the url can cause state thrashing and infinie loops and should be handled carefully.
