User guide suggestions

[eluser]deck42[/eluser]
Two suggestions regarding the user guide - I feel they would be a good idea, others possibly wont

1.) user guide article
Make clear that the extensions do not belong always to the core dir, but possibly to the libraries / helpers dir.

2.) user guide article
Emphasize that flashdata wont be available until the next server request. I would also suggest adding a new function that allows accessing new flashdata but thats another (non user guide) issue.
