Function to compare string to char ftw

Make pas2c happier with uSound

Be more wise about constant initialization expressions being not arrays

Avoid returning an array for the sake of pas2c

fix building with lua (i think)

minor changes for warnings and a variables scope

the ios port runs again, although with a few things to sort out

ios: this commit just removes the overlay class files (with all submenus and resources) while working on a proper restoration

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
