Fix PaymentTransactionGroup_getGroupablePaymentTransactionLineList for case when payment mode is acquired

We have to use the special payment_transaction_line_payment_mode_uid related
key which supports both case when the payment mode is set on line or acquired
from parent (because acquired categories are not catalogued for movements)

use by using "self" on transactional_cached decorator breaks ERP5Site creation due aq_base.

  If the list of bt5 is huge same dependencies are
  calculated several types due recursivity at the
  same transaction making this method useless

change the style of RATE to percentage and add the price_renderer to control the length of the price

This fixes a regression introduced in
commit f36260d2
("Code clean up in ListBox & EditorField").

Make sure convert is not called in case resource is not convertible.

  - Simplify the code and Minor Optimization for sort

  - Now getDependencyList returns entire list of dependencies even
    if it is already installed.

Follow up changes:
  - Included erp5_full_text_myisam_catalog (dependency of erp5_base)
  - Reimplement sortBusinessTemplates for the new behaviour

This is a follow up change of 63c1f784

- when upgradeSite is called, it will delete orphaned bt is we set
  delete_orphaned to true
- when there is provider calculation in the dependency list, look
  at both installed bt and to all the dependency tree
