Make build info **actually** be build info

Before, instead of showing build computer's host name, it would show user's host name. Now fixed by adding some code that executes and generates a temporary header file with app title #defined:  compile_time_code.c
TL;DR gethostname() is now executed compile time so user knows who compiled their build (no longer just shows user's computer name).
