Linter for pubspec.yaml

Based on this discussion at the Sublime Text package repo:

guillermooo/dart-sublime-bundle#94

At the moment, when you run pub install and the pubspec.yaml contains errors, you get error information spat back at you. But there is no sanitize only option; you must run the install process every time.

If you could tell pub to simply check the file for errors, the user could be warned in advance by tools such as Sublime Text.

This is a long-winded way of asking for a pubspecanalyzer in the spirit of dartanalyzer. :)

I'll work on a 'pub validate' command

I wouldn't mind adding this to den:

http://pub.dartlang.org/packages/den

which is focused on pubspec analysis and manipulation, and it should be trivial to add once issue #21169 is fixed.

Of course, I'd be fine with it being in pub itself as well.

The pub publish validation should be part of it as well. If you're doing tagged version commits, you generally want to validate first, then do the commit, then publish. If you wait until publish to find the issues, then you need to redo your tagged version commit.

A number of pub-related lints are being proposed for the dart linter (https://github.com/dart-lang/linter/) and I'm well on the way to having the plumbing in place to start implementing them... Feel free to add ideas there!
