Whitespace changes can be ignored

[carloscz]

Updated git-blame npm module to version 1.1.0 (implements possibility to ignore whitespace changes) and implemented this option into vscode-gitblame extension.

Don't know if it is better to let user choose that he wants to ignore them or not, but I am not profficient with VSCode configuration schema, so it can be maybe implemented by someone else :)

EDIT: added configuration option, defaults on (true) ignore whitespace changes ;)

Is there something else missing I'm might be of help on getting this merged and released? I think this can be useful. Look at this SO question https://stackoverflow.com/questions/4638500/git-blame-showing-no-history Thank you!
