Bugs & fixes in Eclipse & Rachota

Bugs & fixes in Eclipse & Rachota, as used in S. Davies, M. Roper and M.Wood, "A preliminary evaluation of text-based and dependency-based techniques for determining the origins of bugs", in Proc. WCRE, 2011 (http://dx.doi.org/10.1109/WCRE.2011.32)

* Fields are comma-separated and unquoted

* Fields which contain multiple values are pipe-separated

* ? means no result for that field, and can be interpreted slightly differently for each field:

** Origin(s): No origin found. The reason why is recorded in the Origin Class field

** TA Result(s),DA Result(s): The approach would not return any result, or the Origin Class was Unclear

** TA Most Frequent, TA Most Recent: The result of the variation was not recorded, either because it was obvious (in the case of the original approach returning 0 or 1 results) or immaterial (in the case where all results of the original approach are wrong)
