Add Proper Support for Boot

[azizzaeny]

• It Seem Lein Light-table Repl... keep executed, even if we properly connect to boot nrepl with

(deftask lt []
  (swap! boot.repl/*default-dependencies*
         concat '[[lein-light-nrepl "0.3.3"]])

  (swap! boot.repl/*default-middleware*
         conj 'lighttable.nrepl.handler/lighttable-ops))

boot lt repl

• Cannot Eval Build.boot file when connected to nrepl boot, because no proper syntax types support

• Loading indicator keep spining when use boot repl, i dunno why this is happening
