Pass filename relative to cwd to minimatch

[soumya92]

This retains the fix for #1 while allowing use of ** in glob
patterns. Making both **/vendor/**/*.js and !*.json match the
expected files.

No, it should use the relative path to base, not to cwd.

This would help solve #5 though. file.relative is only the filename. ** will never be useful in just the filename, making filtering far more limited.

Consider the tree:
scripts
|-- vendor
|-- public

How would you filter .coffee files in just the vendor folder?

file.relative is only the filename.

file.relative is the relative path from base, which by default is your gulpfile.

How would you filter .coffee files in just the vendor folder?

scripts/vendor/*.coffee?

Huh. Must be something weird in my setup, then. Thanks for looking at this!
