svn properties are all over the place

[johnjamesjacoby]

Lots of Subversion properties are set incorrectly, or have invalid settings.

• Some PHP files have the text/x-php type set.
• Some CSS files have the text/css type set.
• Some files have no eol-style set (should be native)

(In [6093]) Code Improvement:

• First pass at updating subversion properties.
• Remove text/x-php mime types.
• Remove text/css mime types.
• Add eol-style = native property where needed.
• See #4256.

This is done for now? Can we close the ticket?
