Improve display of current param in snippet

[keevan]

The default snippet is currently, okay. But it can be so much better, such as by highlighting/bolding the current parameter when the signature helper is activated.

I've attempted to do this locally and pushed my changes to a fork, but it's not the end goal I want.

https://github.com/atom-community/atom-ide-signature-help/compare/master...keevan:improve-display-of-current-param?expand=1

I want a solution where:

• the current param is very clearly displayed, and the user knows immediately where it is and what it's used for
• existing syntax highlighting for the grammar provided in the snippet to work as normal - my current fork breaks this as a way of circumventing the stripping of tags (bold, strong) or lack thereof (I've tried markdown style as well) when passing the snippet prop in ViewContainer

Ideally, changes would be made there to allow for some form of bolding in that atom-ide-base project, and all might be well, but this was easier.

Also as a side thing, I had an issue dev'ing this package for some reason as I would expect. Not sure if you knew what I might be doing wrong.
Steps:

• Fork this repo
• Clone this repo somewhere and cd there
• Run apm install and for good measure npm install && apm link --dev
• Run atom in --dev mode in target project atom --dev .
• Expect signature to display changes but I get an empty box.
