Update backbone.d.ts

Removed methods from underscore that are no longer mixed in with Collection:
`compact difference flatten intersection object union uniq zip range`

Removed `make` method from `View`: nowhere to be found in 1.0, apparently dates from 0.9.0

Removed `validate` method from `Model`, only the `_validate` exists, I see no sign of ever a `validate` method being called nor triggered.
