prevent ng build from overwriting source files

Okay, that one was scarry as hell. I am sooo lucky I pushed my project to GH before building ng sources prepared for prod....

What I did was opening .angular-cli.json and setting
"outDir": "../../",

as I wanted to store built files next to my project so that I could simply exclude project in gradle. Turns out that was a terrible mistake as ng build --prod decided to nuked my whole UI project for good. Yes sir it did. 10 days of work have been completely vanished from my harddrive. Good thing is that I did push it all to git before...

I would strongly suggest to add safety switches preventing self-destruction in the whole ng-cli project.

.angular-cli.json から始め、../../ の outDir を使用して報告された ng build --prod の動作を再現します。Angular CLI がその出力パスをどのように処理するかを追跡し、プロジェクト外への破壊的な書き込みを防ぐ安全スイッチを定義します。
