setting files mode with remote_directory resource

Problem exists on windows - but it will be probably simillar on unix (i haven't tested).

When you download directory with remote_directory resource, and you want notify another resource when any file in remote directory changes, AND you have at least one executable file in your directory - then remote_directory will ALWAYS notify another resource!

Cause is that ruby on windows always says, that executable has 755 mode, but default mode is 644 - and each time chef tries to change mode to 644 - which obviously fails on windows miserably So each time you get notification.

Workaround is: download zip file, and act upon zip file changes.
