#1473 .7zignore creation

[Francis Silva]

Hi,
I would like to suggest the implementation of a .7zignore file, in the same style as the Github .gitignore, to allow customizing files that should not be included in the compression of one or more folders, thus facilitating the performance of automated backups with 7z .

It's a simple thing, but it opens up a wide range of use for 7Zip.
