Add `import` snippet

[mkhl]

This adds a snippet to import modules into Swift code, tab trigger im.

This snippet hadn’t been dismissed in #18 but hasn’t been added by now, so I’m proposing its addition separately.

How about we allow a few options for the module being imported? For instance,

import ${1|Foundation,UIKit,AppKit,QuartzCore,CoreGraphics|}

(just a few off the top of my head; feel free to change the list)

That’s a great idea!

I went with ${1|Foundation,Cocoa,UIKit,CoreData,CoreGraphics,WebKit|} because that’s the most common frameworks I’m aware of (and the list linked below states that one should prefer importing Cocoa over AppKit).

If we want a huge selection, there are comprehensive lists of

• macOS frameworks
• iOS frameworks but I’d say importing other frameworks is easy enough.

Nice 😄
