Normally cache-tree will not produce trees from an index that has
CE_INTENT_TO_ADD entries. This is a safe measure to avoid
mis-interpreting user's intention regarding this flag.
There are situations however where users want to create trees/commits
regardless i-t-a entries. Allow such cases with commit.ignoreIntentToAdd
for git-commit and --ignore-intent-to-add for git-write-tree.
