support git submodules

[epcim]

if repo has submodules, the commits are not found

Simplest possible solution to add 'git submodule foreach', but perhaps a more sophisticated one would be updating .git directory search algorithm so it doesn't ignore submodule dirs (they have .git as file instead of dir).

Really excited to see this tool exists, bummed to learn it ignores submodules

I found that commenting all these lines will show the commits from submodules:
For a strange reason, this condition evaluates to TRUE and skips the submodule commits.
You need to pass -F though.
git standup -F -d 3 -m 2

# continue if not a git directory
#  if [[ ! -d ".git" || -f ".git" ]] ; then
#   cd ${BASE_DIR}
#    continue
#  fi

Issue still exists in master. Applying the patch in #116 seems to fix it for me. Were there some other issues with the PR that made you close it @mihaicris ?
