When you call SmartSprites with a relative path on Windows it will crash, although the absolute path works fine.

e.g. C:\workspace\smartsprites>smartsprites.cmd ..\web\WebSite\Root

will produce:

Exception in thread "main" java.io.FileNotFoundException: C:\workspace\web\
WebSite\Root (Access is denied)
       at java.io.FileInputStream.open(Native Method)
       at java.io.FileInputStream.<init>(Unknown Source)

       at org.carrot2.labs.smartsprites.SmartSprites.main(SmartSprites.java:46)

and C:\workspace\smartsprites>smartsprites.cmd C:\workspace\web\WebSite\Root functions well.

The problem with the above invocation (actually with both, I'm not sure if the latter would work either) was that SmartSprites expected a file as an argument, but got a directory. To provide the directory with CSS files, use the --root-dir-path parameter. See http://csssprites.org/#global-options for more information on these options.

I've added some extra checks to produce more meaningful messages in such cases. I also improved handling of relative --root-dir-path a bit.
