clomacs-httpd-start FileNotFoundException on Windows 10

Hi,

I'm having troubles starting http server using `(clomacs-httpd-start)`:

```elisp
Debugger entered--Lisp error: (error "FileNotFoundException Could not locate clomacs__init.class or clomacs.clj on classpath. clojure.lang.RT.load (RT.java:456)
")
signal(error ("FileNotFoundException Could not locate clomacs__init.class or clomacs.clj on classpath. clojure.lang.RT.load (RT.java:456)\n"))
error("FileNotFoundException Could not locate clomacs__init.class or clomacs.clj on classpath. clojure.lang.RT.load (RT.java:456)\n")
clomacs-get-result((dict "status" ("eval-error" "done" "state") "ex" "class java.io.FileNotFoundException" "id" "11" "root-ex" "class java.io.FileNotFoundException" "session" "5933c6ef-b53c-4e22-9264-87d6a3825e1a" "err" "FileNotFoundException Could not locate clomacs__init.class or clomacs.clj on classpath. clojure.lang.RT.load (RT.java:456)\n" "changed-namespaces" (dict) "repl-type" "clj") :value :string nil)
clomacs-require((quote clomacs))
clomacs-httpd-start()
eval((clomacs-httpd-start) nil)
elisp--eval-last-sexp(nil)
```

I'm doing some Clojure with clomacs and it's working fine (I'm able to call Clojure functions from Elisp), but I wanted to use callbacks from Clojure to Emacs and have this issue.

I have Windows 10, Java 1.8, Emacs 25.3.1, Spacemacs.

If you need more information please let me know.

Thanks!
Kirill
