Remove dynamic templating steps

[Bios-Marcel]

Currently templating is used for multiple things:

• constant values, such as the drawing board dimensions

• translations (Which is also constant)

• Stuff that's not compile time constant, but runtime constant, such as the RootPath

• Dynamic stuff, such as the LobbyID

The lobby id is only really needed for the socket and can be retrieved from the URL bar.
The other dynamic values can be applied lazily or at startup.

This is a blocker for #369

The goal here, is to optimize response time and reduce runtime complexity, as templating can fail.

I made a little thinking error ... the translation are somewhat constant, but need to be selected depending on user locale. Therefore it might be better to just do it dynamically after all.

Closing this for now.
