Krull dimension for limit groups II: aligning JSJ decompositions

Abstract
This is the second paper in a sequence on Krull dimension for limit groups, answering a question of Z. Sela. In it we develop the notion of a resolution of a sequence of limit groups and show how to derive resolutions of low complexity from resolutions of high complexity.
Consistent with other papers in the series, I hope. Not a major rewrite. The statement of Theorem 1.4 is consistent with paper 4 (the new one) now. (And they have the same numbering, coincidentally.)
