[PATCHES] Documentation for some of my features in 2.13

[Reinhold Kainhofer]

Dear all,
Here are three patches for some features that I implemented during the 2.13 
cycle so far. 

http://codereview.appspot.com/4133044/
http://codereview.appspot.com/4129053/
http://codereview.appspot.com/4132045/

As I wrote in my other mail to the bug list, I prefer it if the developer 
writes some basic documentation, while some dedicated doc writer makes them 
readable to normal users. So, please understand these patches as a suggestion 
to be improved, not as a final version.


Some more patches are yet to come (for pdf metadata, context mods stored as 
variable, etc.)

Cheers,
Reinhold
