[PS2 mod] PC edition - Beta release file

This is beta release of Half-Life: PC Edition mod for PS2.

There are two versions of beta build: full and stable.
- In Full version all models are recompiled: it provides proper autoaim and model textures with more reasonable sizes. So performance is slightly better and there is less texture corruption but it crashes on loading screen every 2-3 chapters.
- Stable version has untouched monsters and weapons models so auto-aim is broken there and texture corruption is more severe.

As far as I tested it works on both PCSX2 and real PS2 (music should be OK now on PS2).

Installation:
PS2) Modded PS2 is required. Burn disc or put ISO file in OPL's "CD" folder.
PCSX2) Unzip ISO and select it in PCSX2 CDVD disc plugin menu.

Known issues:
- Crashes every 2-3 chapters on full version.
- Texture corruption.

Beta release changes list:

- Finally found out what was breaking music on PS2 and fixed it.

- Erased little man sprite from HUD.

- New auto-aim lock sprite. I tried it to make it less annoying and to look like HL2 side bars.

- Fixed auto-aim on all monsters (full beta version only).

- Recompiled all models to downsample textures so they are have more reasonable sizes (full beta version only).

- Replaced first Hazard course map with converted from PC map (converted with BS2PC).

- Replaced ugly dithered skyboxes with a little bit less ugly non-dithered ones.

- Created new models for health stations, hev chargers and retinal scanners so they look like ones in PC version.

- Created new save game pictures. New save pictures are mostly based on Half-life: Source chapter icons.

- Modified crosshairs so they should be more visible now.
