Warn if property does not exist and add it to DiContainerTrait

[mvorisek]

This highly improves code quality as something like:

$m->noLongerSupportedProperty = 'x';

or

$m->eckbox= 'x'; // notice the typo

will warn if the new trait is added. To add it to the most of the code, we add it to DiContainerTrait by default.

The deprecation warnings can be supressed by a custom error handler or by overriding the warnIfPropertyDoesNotExist method.
