Feature Request: Display Inferred Types to the User

[kuza55]

Its often pretty useful to see what the type of an inferred variable or expression is, particularly when reading someone else's code. It would be nice if RustDT could show the types to the user, e.g. when the user mouses over a variable/expression or clicks on it and selects F2.

This would need to be implemented in Racer first: https://github.com/phildawes/racer/issues/304

:+1: Nice to have! Meanwhile looking at the types column in the Variables/Expressions windows at runtime is good enough.
