list posts based on Dossier

[leonieke]

list posts based on Dossier too (date and category are already available in the back end)

(In [651]) use the common _get_posts function in the admin interface as well instead of the hardcoded sql queries. For this I had to edit the function to make some more stuff variable.

I know the backend limit on month/year using the dropdownboxen is not working in devmode. I will fix this when I implement #166 in the backend. Only mvblog that runs on localhost will be affected and not work, all live mvblog installs will work. Beware: if you are running mvblog in a setup with pound that connects to localhost you will be affected as well. (found out the hard way here)

Re #166

(In [653]) make searching for month/year in backend work again. Also disable the limit on active=1/public=1 for the backend.

Re #166

[michiel]

(In [654]) allow limiting on dossier in the admin backend. (Closes #166)
