* Add a *ton* of const and constexpr around the codebase.
This makes the codebase compile without strings being cast to non-const char*. I also went through and added constexpr where appropriate for tons of static data.
* Make process definitions const too
Might as well
* Some dbg work for d_a_e_rdy to get a tenth of % matching. Still some regalloc issues remain
* Change '#ifndef DEBUG' to '#if VERSION != VERSION_SHIELD_DEBUG' per Taka's request
