User blog:Konyvespolc/finally some updates to MW2

as of today:
 * Care Package, Emergency Airdrop, and Sentry Gun marker grenades sprint speed normalized
 * Sentry Guns: Improved placement detection, preventing cases of Sentry Guns inside geometry
 * Model 1887: Bling using Akimbo and FMJ combination now has same range and damage as non-Bling Model 1887s
 * Improved player collision removing cases of getting into geometry and 'elevators'
 * Mouse latency tweaks for more mouse movement consistency
 * Fixes to prevent various texture and XP hacks

hurray!
