355: feat: add ability to customize status bar text r=ehuss a=acheronfail

I wanted to be able to customise the status bar text while the syntax check was running. Here's that change!

It's "non-breaking", meaning that the text is still this:
👌

And it allows you to customise the text like this:
🎉
![custom-1](https://user-images.githubusercontent.com/34289614/48541059-db6dfd80-e90f-11e8-92ea-d69ce89fe810.gif)
😮
![custom-2](https://user-images.githubusercontent.com/34289614/48541061-dd37c100-e90f-11e8-8d50-537f51367226.gif)

Or even this:
