[IMP] mis_builder: number format are now part of styles

Plus a default style at the report level.
Plus correct number rendering for comparisons in Excel export.

mis_builder/CHANGES.rst

@@ -13,6 +13,9 @@ Part of the work for this release has been done at the Sorrento sprint
 April 26-29, 2016. The rest (ie a major refactoring) has been done in
 the weeks after.
 
+* [IMP] There is now a default style at the report level
+* [CHG] Number display properties (rounding, prefix, suffix, factor) are
+  now defined in styles
 * [CHG] Percentage difference are rounded to 1 digit instead of the kpi's
   rounding, as the KPI rounding does not make sense in this case
 * [CHG] The divider suffix (k, M, etc) is not inserted automatically anymore
