Bug fix: expand for ${project_path}

[moonfruit]

when there is no .sublime-porject file in windoes folders,
program throw a excption on line 162

If there is no .sublime-project file, ${project_path} shouldn't be used. Also binary files will not be accepted.

I DO NOT use ${project_path}!!!!
It ALSO Throw a exception on line 162!!!
Variable "project_path" is None, so "project_path.replace" throw a exception
<<<<AttributeError: 'NoneType' object has no attribute 'replace'>>>>>
Do you TEST IT ???

[moonfruit]

AttributeError: 'NoneType' object has no attribute 'replace'

binary files is my fault, I add pull request first, after it I commit binary files.
I do not know, it affect the pull request.
