add: Support specifying an excludes file with a configuration variable

Browse Source 
This adds the 'core.excludesfile' configuration variable. This variable can
hold a path to a file containing patterns of file names to exclude from
git-add, like $GIT_DIR/info/exclude. Patterns in the excludes file are used
in addition to those in info/exclude.
