max_edicts: raise to 8192 (from 2048) and make non-archived, to reduce the need for players to mess with it to get maps/mods to run.

Some measurements on the size of the sv.edicts hunk allocation, with this change, on various mods (it depends on the number of QC entity fields):
id1 7MB, quoth 11 MB, arcadim 21 MB, rrp 9MB,  ne_ruins 16MB.

Since this is a Hunk_Alloc, the whole 10-20MB is cleared to zero which will allocate that much physical ram.
We could probably change it to a malloc later, and not clear the memory, so physical ram is only allocated when the memory is cleared in ED_Alloc.
