Instead of defaulting to a one sentence synopsis for documentation on
hover, allow the user to configure the amount of documentation they want
to see. Right now, the options are none, some (using go/doc.Synopsis),
or all. We should add a 4th, single-line, mode, which will allow clients
like vim-go to stop stripping off documentation on hover.
