KZMod Update - Build 2580 - Bug fixes, requested features

Hello everyone! Another quick KZMod update. This one fixes some bugs and adds some requested features.

Remember to use your Update Kreedz Climbing link or KZUpdate in the KreedzClimbing folder to update. Have fun!

Bugs fixed:

-> Fixed player_jump plugin event not being fired.

-> Fixed the recording player sending chat messages in demos stopping the menu from working when watching the demo.

-> Fixed ljstats (Stats Readout) being cut off at 800x600 resolution.

-> Fixed the game crashing if the localisation file can't be found. Now the game says what the issue is and recommends solutions.

-> Fixed entity inputs AddAllowedTeam, RemoveAllowedTeam and ResetTeam working if a player starts a team timer but doesn't have a full team yet.

New features:

-> New commands: kz_cl_hud_speed_horzonly and cl_showpos_horzonly: Sets those speed displays to only show the horizontal velocity instead of including vertical.

-> Added r_forcedrawviewmodel and r_forcedrawweapons. Forces the game to render the viewmodel or weapons even if the player is holstered. Intended for moviemakers watching demos.

-> Restored player physics interactions (i.e. with prop physics). This was turned off a very long time ago, around Beta 2, due to physics glitches making the player fall out of the map and so on. Now we are on a much better codebase and engine so everything seems fine, physics returns!

This has the effect of re-enabling pushing prop_physics objects and func_physbox, for example.
