Show symbol type on hover

[patrys]

I'm playing with the idea of providing type annotations on hover instead of duplicating autocomplete results. This is quite useful especially when combined with PEP 484 annotations or comments with type hints.

I think this is ready for review now. The behaviour is as follows:

• for classes and functions hover displays the docstring (if available) and the signature
• for modules hover displays the docstring (if available) and the full name
• for the rest (mostly variables) hover shows possible (can be multiple) types inferred by jedi

I've reversed the description and signature to match what other language providers do.

Looks great. Anything you can do to handle very long doc strings, like limiting the hover box height and adding a scroll bar, or is that limited by VS Code?

This is already handled by VS Code.
