Extra features to Feeds module

[hvorragend]

Add categories/sections to the Feeds module.
So you can organize/group different types of rss-feeds as block. 

Example:
[Friends blogs]

friend 1
friend 2 

[International news]

CNN 

[Tech]

Toms Hardware 

[Misc]

some other feed 

Etc..etc..

Maybe also configurable how many rows to display in the view available feeds display.
