Log Message:
Update ruby-activesupport32 to 3.2.13.

## Rails 3.2.13 (Feb 17, 2013) ##

*   Fix DateTime comparison with DateTime::Infinity object.
    *Dan Kubb*

*   Remove surrogate unicode character encoding from ActiveSupport::JSON.encode
    The encoding scheme was broken for unicode characters outside the basic
    multilingual plane; since json is assumed to be UTF-8, and we already force
    the encoding to UTF-8 simply pass through the un-encoded characters.
    *Brett Carter*

*   Fix mocha v0.13.0 compatibility. *James Mead*

*   `#as_json` isolates options when encoding a hash. [Backport #8185]
    Fix #8182
    *Yves Senn*

*   Handle the possible Permission Denied errors atomic.rb might trigger due to
    its chown and chmod calls. [Backport #8027]
    *Daniele Sluijters*
