[FLOW3-general] singleton-annotation for repositories necessary with 1.1 beta1

[Franz Kugelmann]

Hi all,

my feedback and experience with upgrading to FLOW3 1.1:
generally quite smooth, you guys did a great job!
The only thing was, that i had to insert a singleton-annotation for my 
repositories due to a check Karsten implemented shortly, which was 
unexpected.
But the exception for it stated quite clear what needed to be done :)

In the documentation this annotation is mentioned, therefore newcomers 
should not have a problem with it:
http://flow3.typo3.org/documentation/guide/partiii/persistence.html

looking forward to the final release!

Franz
