Cleanup: Remove execute privileges on files.

@alanbly Is there a valid reason why the file permissions were changed to 755?

I'd rather they be changed back for the following reasons:

1. None of the files changed have interpreter directives that would allow the files to be executed on their own.
2. Adding execute permissions is dangerous, as you can have unintended results should the default interpreter be used and you have some command that wipes out the current directory.
3. It's very uncommon to assign the execute bit on a file that doesn't need it.

I'm sure this was an issue with my environment (where this repo sits in situ with an SVN repo) that I did not intend to propagate.

Thanks!
