Dependencies for biblatex and friends

[Moritz Wemheuer]

Hi everyone,

the dependencies for biblatex and friends should be as follows

biblatex depends on
- pdftexcmds
- etoolbox
- kvoptions
- logreq
- ifthen (latex)
- url
- keyval (graphics)

csquotes depends on
- etoolbox
- keyval (graphics)

logreq depends on
- etoolbox
- keyval (graphics)

All biblatex-... packages bundles depend at least on biblatex, some like 
biblatex-apa also require Biber (but I'm not sure if you want to model 
that in the dependencies).


Best
