Install only when dependency is there #14
Description
I see that at the moment there is a warning when either cljs-devtools or dirac is missing in the env.
I have in lambone an optional switch to enable dirac though which at the moment conditionally includes the deps.
It would be great if boot-cljs-devtools could detect that I don't have one or the other in the env and instead of send back an error, just don't require the namespace and don't call the install! on that missing dep.
What do you all think?
