[ADD] account_tax_chart_interval: Tax chart for a period interval

Tax chart for a period interval
===============================

Regular tax chart wizard lets you select only one period. With this module,
you can select an initial and ending period, and you will get taxes data
for that interval.

+Tax chart for a period interval
+===============================
+
+Regular tax chart wizard lets you select only one period. With this module,
+you can select an initial and ending period, and you will get taxes data
+for that interval.
+
+Known issues / Roadmap
+======================
+
+* sum_period compute logic has been completely overwritten when coming from
+  tax chart wizard because there is no provided hook or facility, so changes
+  in the computation upstream (unlikely, but possible) will not be reflected
+  with this module.
