tiny_mce_gzip is getting gzip compressed twice

[welcomb]

Some servers like mine enable gzip on all output by setting output_handler to ob_gzhandler in php.ini. However zlib is also installed thus the check for compression in line 87 of tiny_mce_gzip.php both fails. Because function ob_gzhandler does exist and zlib.output.compression directive is not set.

This causes tiny_mce_gzip to be encoded twice, resulting in gibberish output to the browser.

To fix, insert an extra condition ini_get('output_handler') != 'ob_gzhandler' to line 87.

Looks good to me. +1.

(In [5333]) Don't double encode gzip output if gzip is already set in php.ini. Props
welcomb. fixes #4205

Reopen for 2.2 consideration.

+1 for getting this into 2.2.
