Add Generic Event Dispatcher/Container

[paugnu]

Hi @Vinai,

I've created a new event dispatcher and its container in order to be able to modify any type of data:

Model/HyvaPrefetchEventDispatcher.php

• We only pass 2 parameters to the event: the grid name and the data to be replaced
• The Event Dispatcher will receive this data (no typing can be done here, because the data might be of any type), and will use the HyvaAdminEventContainer to wrap that data and send it to the final event

Model/GridSourceType/RepositorySourceType/HyvaAdminEventContainer.php

• Using the functions getContainerData / replaceContainerData will be enought to do the desired modifications in an observer. This should be documented first in case this PR is OK for you.

Please let me know what you think (and, of course, the things you think could be improved in the release itself).

I've tested this with my custom observer and worked fine :)

Hi, thank you very much! I'll have a look either tonight after work (if I'm able to) or tomorrow morning.
