Feature plan for 0.10

Finally I took some time to write down all the features I'm aiming for the next release. My personal favorite news are the KDE4 look and feel (parallel with a plain and old good Qt4), a new book dock widget to navigate through a user manual and e.g. math figures with (click-to-insert) formulas. Read all the planned (and already implemented) changes. If time and luck allows, the list can even increase, but I prefer to be pessimistic :)
