scripting issues

[lieff]

tcc: tcc needs heavy modifications for web, needs modifications to sandbox file io, ABI issues.

picoc: picoc do not supports floats (only doubles), function pointers, slow.

Ideally we need script->bytecode translator (reuse AVM1?), so player needs support only bytecode, easy sandbox, normal speed, compiler fixes do not affects already installed players.
