fixes#67
- Plugins and the user model were throwing strict messages in php 5.4+
or with E_STRICT on php 5.3 and lower. Should be fixed.
- New cakePHP added automatic HTML5 validation to form fields, which
breaks fields that can alternatively be left empty to not be edited
(such as the password field in user edits) - removed the html5 form
validation from user edits.
If it's just an existing behavior or lib,
place it in a plugin directory structure in <cydefsig>/plugins.
If there is a need to change an extern existing plugin,
extend the existing plugin by a new plugin in <cydefsig>/app/Plugin.
This way there is a very clean devision between own and external code.
The external code can be updated without touching own nor changed code.
