Title: Fixed compile issues on windows.

With latest upstream L-Systems treegen compiling on windows would fail due to a few things.

The issues where: round() is not part of math.h in MSVS so I've changed it to use myround and included the numeric.h file, M_PI was undeclared so I have also included the mathconstants header and finally line 284 was causing issues because of the use of "and" instead of "&&".

Also the include header for irr_v3d.h couldn't be found as it wasn't set to look in both local and predefined directories.
