[PEPr] Changes in proposal for Networking::PEAR2_Net_RouterOS

Vasil Rangelov (http://pear.php.net/user/boen_robot) has edited the proposal for Networking::PEAR2_Net_RouterOS. Change comment: * Added the ability to convert between charsets on-the-fly using the new get/setCharset() and get/setDefaultCharset() methods (particularly useful for making output appear consistent between MikroTik's Winbox and the web). iconv is now an optional dependency because of this. * All "array of responses" are now a ResponseCollection, with this class offering some convenience methods for filtering the responses (e.g. by type). Implements SPL interfaces to mimic an array. * Added and altered a lot of the test suite, since it often assumed an array. Also made it comply with PEAR coding standards (minus doc blocks). * Other miscellaneous changes. Please review the proposal: http://pear.php.net/pepr/pepr-proposal-show.php?id=664
