Add aliases for submodule updates to gitconfig target

Updating submodules seem to give people headaches, so this adds a pair
of git aliases to update them.

'git sup' updates the submodules to the latest versions, but leaves any
locally modified files.

'git sup-destroy' will remove the current submodules and re-initialize
them.  This deletes any local changes.
