nishang: remote HEAD refers to nonexistent ref

First, thank you for an excellent tool - the search function and organization of packages is extremely useful, even on Kali systems.

This doesn't seem to be a problem with kali-tools per se, but one of the git repos in data.py, corresponding to nishang, seem to be having some issues:

$ ./kali.py nishang
 _  _    __    __    ____     ____  _____  _____  __    ___ 
( )/ )  /__\  (  )  (_  _)___(_  _)(  _  )(  _  )(  )  / __)
 )  (  /(__)\  )(__  _)(_(___) )(   )(_)(  )(_)(  )(__ \__ 
(_)\_)(__)(__)(____)(____)    (__) (_____)(_____)(____)(___/

Please run the program in dist/ nishang

However, this seems to be an issue with the git repo itself:

$ git clone git://git.kali.org/packages/nishang.git

Most of the other git repos I tried worked okay though.
