Fixes #1ef7570.
We implement our own autostart-aware lsp register function. Any lsp
which has the option {autostart=false} set at their config root will be
not automatically enabled and can instead be enabled on demand.
Added script to sh base package to allow checking for internet
connectivity. Checks both through system virtual filesystem and, as a
fallback, through pinging google dns.
Added a simple readme to sh module.
