Default `g:ale_disable_lsp` to a new mode `'auto'` by default. With this
setting applied, ALE will now check for the presence of nvim-lspconfig
and automatically turn off particular LSP linters if already configured
via nvim-lspconfig.
For users that do not use `nvim-lspconfig`, everything should work as
before.
This patch adds support for opening jdt:// links on "go to definition" requests returned by Java language servers.
