Fix identifiers case in uLandTemplates (too lazy to make proper implementation in pas2c)

Declare Param* functions

Fix for Int type and sysutils in hwengine.pas

Some work to make more units compile after conversion to c

Support overloaded operators on (hwFloat op hwFloat) calls

More definitions and mess with pascal code

Render function variables in struct with no mangling. 13 C units are compilable now.

Handle function type differently

Some more definitions and slight fixes

uAmmos.c now compiles (3 warnings though)

Implement built-in functions Low() and High()

Reflects change in previous revision to uTypes

(PointerTo (SimpleType _)) could be a pointer to a non-struct type

Prepend unit name to function identifiers

Mangle overloaded functions (only different number of parameters is supported)

when Lua is not found, fallback to compiling the one that comes bundled in our sources

invert LUA symbol meaning and avoid hints when compiling without it

add support for FPC and FPFLAGS cmake arguments (helps crosscompiling)

old typed const moved to their proper unit

the scope cleanup continues...

split OnDestroy across the appropriate modules (this doen't cause leaks on mobile, right?)

revisit isTerminated in hwengine

fix more breakage

removed the default argument in uWorld

fix breakage

adjust the scope of a few uSound variables and functions

Merge

Convert namespace from list into map in preparation for implementation of overloaded functions support. Greatly improve speed of rendering as a side effect (parse + render time reduced from 5:20 to 0:20)
