ahl_rc2.1_hotfix_beta.zip fixes:
- client.dll radio crash
- ahl.so func_tankrocket/rpg_rocket crash (now does nothing instead)


Linux server concerns:
- ahl.so may require a newer libc6 version. I have only tested 2.42 and 2.43.
- liblist.gam previously used "dlls/ahl_i386.so" for gamedll_linux, but something internal to hlds has started doing s/_i386.so/.so/ for all dynamic library paths.
