fix /usr/bin/env: 'node\r': No such file or directory

[ryantate13]

Use Unix line endings on cli.js to fix crash on Linux

[glensc]

indeed. this is problem on linux.

$ /usr/local/bin/subdownload
: No such file or directory

the #8 fix is bogus and doesn't fix anything

[glensc]

merging this would also close #3 and #4

but the maintainer has to publish new npm version

[glensc]

seems the @ryantate13 fix also doesn't change anything. just renames file two times.

i'll submit another PR with the proper fix

[glensc]

hmm. seems the problem is the way release is made. the cli.js is ok in repository, just when checkouted on windows and released from there, the files end up with DOS EOL.
