submodule_git2https.sh

# Sometimes i need to use HTTPS over GIT because of proxy problems.
# This script changes the .gitmodules from using the GIT protocol to
# using the https protocol.  After that, it initializes the submodules 
# and updates them. Then it reverts the file back to its original GIT format
# Example: 
# URL using GIT protocol:
#   git@github.com:tpope/vim-fugitive.git
# URL using HTTPS protocol:
#   https://github.com/tpope/vim-fugitive.git
