at same time, rename gmt_timezones to all_timezones

Note that after applying this change it's important to clear preferred timezone
for system preferences, as they have priority over user preferences

Also enable pretty printing of kw and activity_kw

* Use editable fields with `pre` style for listbox columns
* Display h:m along with start date

Also fix a naming issue with one field

When searching accounts by validation state, the stat of number of movements on an account could be wrong

ERP5Site.log and Base.log are wrappers to the 'log' function from
Product.ERP5Type.Log, but parameters were forwarded in a wrong way
when called with a single argument:

  self.log(message) # Base method

This was equivalent to:

  log(message, '')  # function from Product.ERP5Type.Log

And the whole message was later part of subsystem in:

  logger = logging.getLogger(subsystem)

But because loggers are never freed, it is important that 'subsystem' does not
vary too often, to avoid a memory leak.

The fix is to simply forwarding parameters with catchall arguments, instead of
duplicating the signature from Product.ERP5Type.Log.

Of course, it remains important to call these methods correctly, otherwise
memory leaks can happen again. For this reason, catchall arguments also
prevents ERP5Site.log and Base.log to be called by ZPublisher.

Now you can sort results by full text search score, for example.

Now we have explicit ORDER BY in the outer query so that we no longer need
to disable derived_merge optimizer.

- group_by, group_by_expression -> group_by_list
- select_list, select_expression -> select_dict
- sort_on, sort_on_order, order_by_expression -> order_list

It is useful when use select_expression in inner query and use
group_by_expression or order_by_expression in outer query.

Revert "Add auto_extend_select_list argument in buildSQLQuery() and use alias in group_by_expression and order_by_expression."
Revert "Support group_by_list and order_by_list in WebSection_getDocumentValueList."
Revert "Support order_by_list in Resource_zGetMovementHistoryList."

No need to extend SQLCatalog parameter to support group_by_list and order_by_list in sub-queries.

It should be only for the case where no predicate criterion exists at all.
