Ensure all .bat and .sh scripts in the distribution have the correct line ending.

It is possible using .gitattributes to specify the endings to use for different file types, however this seems a bit temperamental when checking out different branches with different endings.

To be safe I think we should just ensure all scripts copied to the AS distribution have the correct ending for their target platform.

Scripts used within the build are not as much as a risk as they are going to be checked out on the target platform that is defaults are used are more likely to default to the local platform.
