ChangeStateForm: extract method redirectpath() for easier subclassing

EditBox: extract workflow actions construction in a separate method

fix interface_selector bug If a view using this selector defines an `accepts` attribute, the view should be selectable only if the entity is of one of the accepted types (+need to consider schema inheritance)

if EntityBoxTemplate now uses _rqlcondition_selector, it must also define a default condition attribute

upload icon (actually just the download icon rotated)

merge

code moved to logilab.common.logging_ext

cleanup

only hide strict suboject in default view

check we don't get selection ambiguity: if yes, log error in production env, raise in other modes

don't ask confirm

add _rql_condition selector to default EntityBox selectors

get actual exception class instead of 'unicode' in the error view

TreeMixin : provide an iterator on the parents

merge

updates done to documentation after following instructions for a new cube

use repr (instead of str) to print rql in __repr__ method of a result set

don't systematically init_log, it may breaks client log configuration

fix default values

don't change Pyro.config here
