Warn on directory compare when there is no diff tool configured

[aminpaks]

I never could get this to work!
I follow these steps:

• >GitLens: Directory Compare
• Pick one remote branch
• Enter

Nothing happens!

Any help?

@aminpaks you'll need to have git configured with a difftool. Do you have that setup?

[aminpaks]

No I thought it's part of vscode!
How to do that?
Would it possible at least interact with user if it's not setup yet?

[eamodio]

Vscode can't (as far as I know) do directory compares. Would need another difftool like Beyond Compare.
I will look into either hiding or providing some feedback on those options if it isn't setup

[aminpaks]

Thanks in advance.
But if vscode team can provide this ability that would be so good!

@aminpaks FYI microsoft/vscode#6898

Hi @eamodio,

an error message window pops up with no text shown, if the diff.tool is not set (via git config --global --unset diff.tool). Using the current version 1.11.0 (1.11.0).

I just started using your fantastic tool. It's very nice. Thanks for that.

@Dominik-K thanks for the report -- this is fixed in v3.2.1

Would it be possible to change this so diff.guitool is used instead (and that git diff is executed using the --gui flag)? I would like to use a GUI tool when running a diff from within VSCode but keep using the default when diffing in the shell.
