cygwin filepath support

[tsulej]

Can't invoke commands which requires file load on the refactor-nrepl side. For example rename symbol.

After some debugging I found that problem is similar to this issue: clojure-emacs/cider#735
And instead of simply slurp filename should be treated by cygpath before.

Actual behavior

Calling rename symbol causes following exception:

cljr--get-error-value: Error in nrepl-refactor: java.io.FileNotFoundException:
\home\tsulej\clojure2d\src\clojure2d\color.clj (System nie może odnaleźć określonej ścieżki <--- can't find path)
at java.io.FileInputStream.open0 (:-2)
java.io.FileInputStream.open (:-1)
java.io.FileInputStream. (:-1)
clojure.java.io$fn__9520.invokeStatic (io.clj:229)
clojure.java.io/fn (io.clj:229)
[...]

nrepl debug shows such messages:

Steps to reproduce the problem

Under Cygwin I run startxwin to run X Window System and run Emacs, open file, invoke cider-jack-in or connect to extrenally run REPL. C-c RET r s causes error.

we should use what is already in cider from clj-refactor I suppose

[tsulej]

I see that I mistakenly assigned bug here. Bug should go to the emacs side (clj-refactor). Emacs under Cygwin has native converting functions. Info.
I'll try to make some tests.

Move it if you want, but we're kind of used to closing issues across these two repos so it's not really a problem @tsulej.
