GNUnet 0.6.1c released

This is yet another bugfix release.  The new release fixes: 

* an integer underflow that sometimes reduced download performance to a crawl 
* weak-key failures with libgcrypt 
* a 64-bit size_t problem on linux/alpha 

Furthermore, 0.6.1c features: 

* higher context sensitivity in the routing algorithm 
* explusion of peers that ignore bandwidth limitations 
* initial bandwidth limitations (to guard against the jetstream effect) 
* more aggressive query frequency at the end of downloads 
* minor code cleanups 

Migration from 0.6.1b to 0.6.1c should require nothing but recompilation.
