Drop MirrorRecorder

[Vadim Gritsenko]

Hi all,

While revamping i18n found this curious thing -- 
o.a.c.transformation.helpers.MirrorRecorder. New i18n transformer will 
no longer use this class, and will be based on SaxBuffer instead.

Is there anybody or anything using this MirrorRecorder? Please yell 
before I kill it...
