Implement Hover Request

[AnHeuermann]

Description

Implement server capability Hover Request.

The hover request is sent from the client to the server to request hover information at a given text document position.

Desired features

• Documentation on hover
  • Display doc-strings of classes (so every model, block, type and so on / everything's a class in Modelica)
  • (Optional) Display documentation annotation of classes (basically HTML)
  • Input and output types and doc-strings
• Server test
• Client end to end test

Example

In TypeScript this looks something like

OMEdit displays the doc-string of the class when writing, but not the documentation annotation.

I am currently working on it.
Right now the server only recognizes line comments above a class.
