Simple LSP server

This version brings an initial implementation of an LSP server, which will emit diagnostics based on the already present scanning, parsing and resolving steps.

The server is available through the executable pinto_server, which is provided together with the default pinto executable. It can be used with the VS Code Extension.

Other changes:

• Now, a resolve error is emitted when importing a package that's not available in your environment.

Small fix in compiler

There was a bug when compiling the following code:

type A(T) = A([T] list)

As T was not being used directly, the generated class would not have <T> as a type parameter.

This issue has been fixed.

Full Changelog: v0.0.1...v0.0.2
