Torne Wuff 569285794b Bulk convert all DOS line endings to UNIX.
For the git migration we want a nice clean repository with UNIX line
endings. git does not use svn:eol-style, we just need the file contents to be
sane.

Sorry everybody. I know this messes up blame.

Scumbag *NIX developer says migrating to git will make line ending issues go
away; commits giant change to svn which changes line endings anyway. :)
