Skip files in .gitignore and alternatives

[lduran2]

Skip files that are in .gitignore.

Currently, you can add the unzipped directories to .gitignore. However, this is about saving time on commit. There are currently 3 alternatives

1. enhance .gitignore of unzipped directories by using these to filter unzipping
2. use the zip files as filters for .gitignore
3. check which files are currently added.

Option 3 contradicts current behavior which unstages a zipped file once it's unzipped. So this may require an additionally hook to add the file back presumably after commit. This may be closer to expected behavior.

Option 3 is the best choice. Currently zipped archives will leak onto new branches.
