The Saros implementation will be based on the Language Server Protocol
(see https://microsoft.github.io/language-server-protocol) for data exchange.
In order to enable VS Code to understand that protocol the VS Code language
client has been added. Furthermore starting of the Saros LSP Server
has been encapsulated.

Unintentionally removed parts have been
readded (lsp) and code has been improved
regarding guidelines. Overall quality has
been improved. Vscodes extension build,
run and publish workflow has been shifted
from npm based to gradle base to embed
it better into the gradle environment and
to enable easier CI builds.

In order to keep the size of the extension rather
small the building method has been changed
to webpack. This also brings the benefit
of excluding files that aren't really needed.

Introduce eslint and modify code accordingly.
Furthermore gradle has been modified in
order to seperate config and execute statements.

This commit will add the functionality of
managing accounts and contacts of
Saros. There are wizards for handling
those data and necessary UI elements
such as the contact and active account
view.

This commit will add the functionality of managing accounts and contacts of Saros.
Basic functionality like logging and config
exchange is also implemented. All classes
that will contain logic of Saros from a later
stage will be mostly empty.
