NewsLeecher 7.0 Beta 3 changelog

NewsLeecher 7.0 Beta 3 brings the following changes:
*: In the previous beta, the "Repair and Extract" PAR2 file
   *repair* engine got a major performance boost.
   In this beta, we have looked into optimizing the "Repair and
   Extract" PAR2 file *verification* engine as well. It is now
   300-400% faster than before.
*: Many smaller speed improvements.
!: Fixed bug '14w10j09h' that got triggered when Repair and
   Extract was handling PAR2 files, with some specific keywords
   included in the filenames :

   work properly in the last few betas. This has been fixed.
