Row selection checkboxes broken in Joomla! 3
Added JLayout support for FOF

Implements JLayout for FOF with the addition to look for version specific files and overwrites like default.j31.php, default.j3php, default.php
I did it a bit to complicated, reduced lines of code

The tags helper would fire on delete even when the table was marked as having no tags
changed var _hasForm to protected to allow changing in a derived class

Having the variable privat makes it hard to use a form in a custom task. I have a custom workflow:

add -> preview -> change -> preview ..... -> save
			|
  			-> save

This is made with two custom task "preview" and "change". Change is almost that same as add but without resetting the model, I can't use edit because my data are only saved in the session.

Fixes gh-135 Documentation update
Added some OnBefore and OnAfter functions in form management to allow easier manipulation
made sure data changing is allowed in preprocess when it is an array

That can be a BC problem but I think it makes sense to allow also data manipulation within the form processing. It is only an option because when we add the onBeforePreproccess function it is also possible to do so, that's the reason why I made it as a separate commit :-)
