Normalizer. What features needed out of box? #1

Linkification process expect 2 additional steps:

1. Links normalization
2. Text normalization

Adding too many features tend to api clobbering. Instead i'd prefer to simplify modifications. Some things i know about (with unknown usefulness):

• text
  • decode encoded texts
  • drop http:// (but don't drop for links with user/pass)
  • drop www
  • cut length (leave domain & tail, cut the middle & query)
• url
  • usually, nothing needed, but it would be nice to correctly encode host + path + query

1. It would be interesting to get feedback from big deployments, how do they care about links.
2. Do we need to enchance normalization in this pkg, or move to plugins?
