avoid floating point desync, other script tweaks

So. A while ago, while trying to prevent hogs blowtorching getting turned around, unc0rr altered the old range of blowtorch from 1/8th of 180° up or down, to a 4° gain in upwards and a -4° loss in downwards. He also made it so that starting tunnels could fail to erase sufficient terrain, trapping hogs. Here are a couple of workarounds to more closely approximate old behaviour (do some initial erasure, adjust min/max angles)

Safety check. The main place this can be a problem is on a mild bowl w/ multiple hogs. Could possibly add a hog collision check in here.

split version information in engine too

drop useless option, automatically set revision and debug info

split cVersionString into its three separate components (version, revision, hash) and apply the new values sensibly on the frontend (esp. title, info and feedback)

mysterious merge

support WARNING message status on cmake 2.6 (bug #524)

correct copyright header on files i added

use NETGAME_DEFAULT_PORT macro across frontend sources

move weapons line away from hwconsts.h so that modifying it doesn't needlessly recompile everything, introduce a way to try documenting which weapons each number represents

add icegun everywhere (default, crazy, 1oe) with a qt prob delay crate of 2

close branch

add 'One of Everything' in the weaponsets, from nemo's idea

merge icegun branch w/ default

Merge

Draw ice on water

Make refactoring. Remove DrawIce function

small update of german engine translation

aaagh. remove dead code. again.

Apologies if jaree had done something similar, but didn't see anything in repo pull. This removes Land[] mixed w/ LandPixels[] and streamlines things a little

physfs strikes back

define ice edge colour

enable asm only on intel/amd machines
