    Ignore *.tar.gz
    
    `make dist` and `make distcheck` package MouseTrap for distribution
    into a .tar.gz file. This file is placed in the root of the
    MouseTrap project folder. We do not want this inadvertantly
    committed into our repository. This commit adds a line to .gitignore
    to ignore such files.
