mimetype renderer selection by mimetype fails with charset

[Shun-ichi Goto <gotoh@…>]

IHTMLPreviewRenderer.get_quality_ratio() takes 1 argument mimetype. All the implementation of get_quality_ratio() does not consider for charset attribute in mimetype (specified by svn:mime-type), like: "text/x-rst; charset=Shift_JIS". As result, expected renderer (i.e. ReStructuredTextRenderer) is not selected.

In case of above, "text/x-rst" should be passed to get_quality_ratio() instead of "text/x-rst; charset=Shift_JIS". Here is the simple patch:
