Task: Migrate To Eclipse

@@Home -> ProjectPlanning -> TaskMigrateToFreeIDE

What

After close look Eclipse has been rejected because it is much more Java, but has weaknesses for C++ - too slow, debug is unavailable
Codelite is chosen as next target IDE for migration

findings:

Except Codelite itself, MinGW required and OpenSSH (used for Clean)
-static required to avoid MinGW runtime dlls to be used
link order should used accurately - e.g. aiconsole requires first linking to aiapi, then to ws2_32

changes in the code:

"for( int x" - x now is inside for block, not visible outside
when passing class function as argument from class method, g++ requires using construction:

"&<class>::<function>"

"thread" keyword is unsupported by g++, changed to Tls function calls
g++ has found several errors in unused template functions
now commented C++ handling of SEH exceptions - TBD
static string data require const keyword in g++
more strict checking is for pointer conversions in C++ under g++ - unable to convert implicitly `void` to `char`
varargs is no more supported in g++ - replaced with stdarg version (in fact varargs existed before because of UNIX compatibility issues)
varargs now puts char/short as int to stack
generic headers have been updated - checked in new generic version to aiengine
not resolved question - moment type is now stale - its calendar limit is overdue
found non-english constants for calendar terms - replaced with english ones
unicode constant is not `ushort*` - forced conversions, needs investigations - TBD

L"<string>"

for g++ HINSTANCE is not `void*`
min, max macros are defined in system headers - added #ifndef blocks
`__int64` is replaced with long long int
C-level MSDEV-specific `__try/__catch` was replaced with try/catch - don't know about impact on functionality

change, done by the way - all projects now conform to common structure rules - see related section at DevelopmentEnvironment
