Warning when a big text file is not gitignored

[naholyr]

That's most probably when you forgot to add a gitignore file or just forgot to ignore you dist.js file. Copycast should warn user, and even maybe interactively ask if he wants the file to be ignored (just for the session or added to .gitignore?).

• Step 1: warn user
• Step 2: automatically ignore file (if confirmation from user) in memory or in gitignore file (whatever we choose)
