Fixes Inflector#titleize to work with SafeBuffer

The way Inflector#titleize was implemented did not work properly when
called on a SafeBuffer object. Using the global `$&` variable in the
gsub resulted in calling capitalize on a nil object for reasons I still
do not fully understand. Removing the UNSAFE_STRING_METHODS override for
the gsub method in SafeBuffer "fixed" the bug but is obviously
unacceptable.

An example of this is very easy to see in rails console:

    ActiveSupport::SafeBuffer.new("my test").titleize
    > NoMethodError: undefined method `capitalize' for nil:NilClass

Using the non global version of gsub with a |match| arg passed to the
block fixes the problem. Again I do not quite understand why. I noticed
that other parts of Inflector were already using the standard block arg
version of gsub so I don't think it should be a problem to convert this
method to using it as well.
