Log:
[CONUTILS]: Create a C library for console output/input functions, last-error messages
display, etc. to be used for all of our internal command-line utilities. Useless
user32.dll dependencies are removed thanks to this lib. Currently only output functions
are supported.
CORE-10504
[EVENTCREATE]: Adapt EventCreate to use ConUtils library, as an example of how to use this
library.
