http 400 while addings links(and python client bug)

hi.

sorry for replying myself ;)

the header hits the 8k size mark, that causes the 400.

is there a way to configure the max header length for the rest api's 
http server? like apache's LimitRequestFieldsize?

also there's a bug in the python client lib, the links are qouted but 
not unquoted. this leads to "growing" and wrong tag names.

patch for __init__.py:

1650c1650,1653
<                                 link = RiakLink(matches.group(2), 
matches.group(3), matches.group(4))
---
 >                                 bucket = 
urllib.unquote_plus(matches.group(2))
 >                                 key = 
urllib.unquote_plus(matches.group(3))
 >                                 tag = 
urllib.unquote_plus(matches.group(4))
 >                                 link = RiakLink(bucket, key, tag)


cheers,

alexander
