codemirror python's completion just complete on builtins, so that hack is a bit better

The real motivation was to make sure that search match is displayed when searching with Ctrl+F / Ctrl+G

codemirror: display an animation in window title so that the window flash when component has been saved.

This reverts commit f0808ac6.

Otherwise test will fail because the user is not indexed yet

test: update causality state explicitly because normal users have no write to modify in solving state.

Because solve() is now unrestecred method.

they are mostly 'Modify portal content' permission.

With ZODB Components, getBusinessTemplateList() only returns the test
bt5 (as given on the command line, such as BT_TITLE:testFoo) and later

1. On Tab1, from PurchaseSupply_view, click on 'Purchase Supply Lines':
   Base_viewListMode??proxy_form_id=PurchaseSupply_view&proxy_field_id=listbox

   This Python Script initialise 'list_mode_proxy_selection' with the
   above 2 GET parameters and then displays PurchaseSupply_view.listbox
   indirectly but current Form is Base_viewListModeRenderer.

2. On Tab2, from SaleSupply_view, click on 'Sale Supply Lines':
   Base_viewListMode?proxy_form_id=SaleSupply_view&proxy_field_id=listbox

   This Python Script initialise 'list_mode_proxy_selection' with the
   above 2 GET parameters and then displays SaleSupply_view.listbox
   indirectly but current Form is Base_viewListModeRenderer.

3. On Tab1, filter Purchase Supply Lines.

   As proxy_form_id and proxy_field_id are not given, then

   values to find out the Form ID to be called and wrongly display
   SaleSupply_view.listbox (2.).
