* Compressing a GIF file if not already LZW compressed.

* GIF:
* If $type is not set, the compression is done with ImageMagick (provided that $GLOBALS['TYPO3_CONF_VARS']['GFX']['im_path_lzw'] is pointing to the path of a lzw-enabled version of 'convert') else with GD (should be RLE-enabled!)
* If $type is set to either 'IM' or 'GD' the compression is done with ImageMagick and GD respectively
* PNG:
* No changes.
*
* $theFile is expected to be a valid GIF-file!
* The function returns a code for the operation.
*
