Thanks for the PR. Unfortunately there are several issues that need to be resolved before it can be considered:

1. Please restore the original LF (not CRLF) line endings. Currently the diffs cover 100% of the files and it's impossible to see what actually changed.

2. Please remove the .gitattributes file. I don't want this in the repo. 99% of it is specific to file types that will never exist a WoW addon, and where it does specify a line ending style, it doesn't match the one used in the addon already. Setting git config core.autocrlf appropriately for your platform, and (optionally but ideally) configuring your editor not to clobber the line endings in existing files in the first place, is a better solution that doesn't require extra stuff in the repo.
