Set keywordprg rather than mapping <Space>

Mapping space interferes with user mappings beginning with space. The standard way to set "help" is to use keywordprg. In this case, I suggest

command -buffer -nargs=* ALEHelp call ALEInfoOpenHelp()
setlocal keywordprg=:ALEHelp

Interesting. I'll give it a try.
