Added semantic token support for flag members in the language server
Added property documentation to the hover tooltip for notify signals
The language server now shows relevant sections of the reference documentation when hovering over keywords and symbols

The formatter removes trailing whitespace from comments (Alexey Yerin)

Addressed a problem with the language server protocol in some editors (Luoyayu)
