Account Analytic Plan Required

This module extends account_analytic_required and adds 2 policies to control the use of analytic distributions. The policies behave as follow * never: no analytic account nor analytic distribution allowed * always: analytic account required * always_plan: analytic_distribution required * always_plan_or_account: analytic distribution or analytic account required * optional: do what you like,

In any case analytic account and analytic distribution are mutually exclusive.
