Remove broken unused and unfinished apps and libs

- TEAtool: A useless utility for encryption with the TEA algorithm,
  written for fun by me during my school years;
- GameHack: not a working prototype of a program like Cheat Engine;
- microtar: port of a portable library with a reduced functionality
  for working with TAR in C that is not used
