[Inkscape-devel] _load_uri fix

Whether or not we're in a hard freeze yet, I thought I need to give a heads up on a bug I just discovered and fixed. The function _load_uri in extensions/internal/svg.cpp did not convert the UTF-8 uri into local filename encoding. (Jon Cruz & me added these conversions to all places we could find, but this function was added by Bryce more recently, in the 0.42 cycle). Therefore filenames with Cyrillic characters did not work from command line or from recent file list. Now fixed, please test and review.
