Increase freezetag starting armor from 0 to 100

In a gametype where everyone spawns with all weapons, 100:0 is woefully inadequate and makes a player's chances too dependent on getting a good spawn (near a big armor, not in full view of multiple opponents). It's too frustrating getting fragged in 1 or 2 shots in the first few seconds of the round, and no amount of skill is sufficient to be able to always avoid it.

With this change map knowledge and movement skill are still rewarded, but players without still have a fair go, and might last long enough for some of the items to respawn.

This has increased the popularity of FT on my server significantly.
