erp5_web_jabber_client: Allow user to send multi-line messages

User can change between single-line and multi-line mode

/reviewed-on nexedi/erp5!114

The set of resources correponding to a given (non-strict) use is generally
constant, while the number of documents having relations to these
resources will increase over a site's life.

The original query used 2 joins:
- catalog to category for document/resource relation
- category to category for resource/use relation

Given several tables joined together, MySQL query optimiser will try
to first execute a query on the table which will yield the fewest rows.

As a result of all the above, query optimiser would end up choosing to
first find which resources have a use relation to given uid, and only after
find which documents have a resource relation to these. Which means it
cannot use any index on the documents themselves, and only an index
on resource's use... Leading to extremely poor performance on large data
set when, for example, trying to list the few documents in a given state
which also have a resource of selected use.

Instead, lookup the list of resources per (non-strict) use when building
the domain tree, and put that pre-computed uid list as membership
criterion: catalog query is then only a single-join, whose execution is
trivial to plan.

User can change between single-line and multi-line mode
using one button.

1.8.3 is now required to use profiling.
It provides two important features:
- SQL query tracing (which queries were executed, how many times,
how long did they take to run)
- ZODB __setstate__ per-oid statistics

- contentValues(filter) is really slow
- portal should be explicitly retrieved before using one of its methods

* for bulk substitution, re.sub is much faster than join of dict
  lookup result per byte.

Check that if only the code of a PythonScript (_body) is different,
it will be identified as modified.

For scheduled workflow transition. Use in your workflow transition as:
%(content_url)s/Base_viewScheduleWorkflowActionDialog?workflow_action=%(transition_id)s&next_workflow_action=SOME_ACTION
(replacing SOME_ACTION with some appropriate value).

Delayed workflow transition works with 3 states:
- initial state: where we are
- final state: where we want to go
- waiting state: where we wait for the right time to transition to final state
The main advantages of the waiting state are:
- prevents multiple transitions from being scheduled
- allows customising object security (ex: preventing unwanted edits)
- allows storing intended execution date in a transition comment

Do not require caller to cast between these types when they can all make
sense to appear in the same list.

in most cases, where ASCII-range characters are less than 80% of input
non-utf8 string, the result is same but we can reduce needless string
replacement calls. in rare case, for example wrongly iso-8859-1
encoded properties or PDF data, the result becomes different, i.e.
before: ASCII-range characters + escaped characters => after: base64
encoding, but the meaning is still same.

* stop using deprecated string functions.
* reduce lambda creation inside functions.
* move import statements outside of function.

* remove needless copy of sub objects that are already recursively
  copied by their top most object.
* remove needless manage_beforeDelete() calls when copying objects.

- Document_viewSVGEditor/my_data changes web illustration content type
- WebIllustration_viewSVGEditor/my_text_content does not change it

Installation of business template may change the encoding of a document to utf-8.
Nonetheless, export should preserve the original encoding.
This test creates a ZopePageTemplate with output_encoding of 'iso-8859-15'
and checks that while installed version becomes 'utf-8', when exported it
keeps the original one.

Only xml metadata should be exported in this case.
In the previous version the check of hasattr could pass
if attribute is defined as an attribute of the class and not of the instance,
causing also AttributeError later when the code tries to invoke delattr.

Also, restructure export. First try to delete property and then
export as separate file.

Test also added.
