Basically this makes .ss files look good again and adds a few snippets to .ss files and .php files that I found handy.

Open Preferences -> Settings

Add below settings to enable Emmet for blade:

"emmet.includeLanguages": {
    "silverstripe": "html"
},
"emmet.triggerExpansionOnTab": true,

Snippets are taken from: LiamW's SilverStripe Atom bundle. Grammar taken from: benjamin-smith's SilverStripe Sublime bundle

Go for gold, if it adds value, add it and I'll merge it
