Implement Autosave on Collections, Environments and Requests

[CookieMonster70]

I'm used too, that my IDE is autosaving my stuff and and I also have configured VS Code to autosave my files, when it loses focus. But if I work with thunder cliet, I always have to press CTRL+S to save what I have changed. For e.g I change environment on a collection and I forget save and I'm goging change some where else something then setting is lost. The same happens when you change something on a request and you want to look on another request the your work is lost.

Thanks @CookieMonster70 for the feedback, will review it.

I would love this. Have lost work multiple times since there is no warning when closing modified requests. :/
