Theming: Distinguish between `import` types

In Atom, we can theme imports based on the type of thing being imported. As you can see below, import aliases/names are styled differently than the class Knex being imported. This has always been immensely handy for at a glance differentiation and validation of imports as well as for organizing imports.

Below is the same theme applied to VS Code, but without the ability to differentiate.

I believe this comes down to a lack of TextMate scope. Here are the available scopes for makeContext:

variable.other.readwrite.alias.ts
meta.import.ts
source.ts

And the available scopes for Knex:

variable.other.readwrite.alias.ts
meta.block.ts
meta.import.ts
source.ts

My ignorant suggestion: it would probably be enough to catch capital-cased aliases for adding an additional scope.

Start at the TypeScript grammar rules involved in makeContext and compare the scopes shown for the import alias and Knex. Determine how imported names are currently classified and define the distinct scope needed for theming. Done means import aliases and imported classes can be styled differently, with the resulting scopes verified against the example.
