Added how to commit and contribute docs to pig wiki

[Alan Gates <ga...@yahoo-inc.com>]

I've added http://wiki.apache.org/pig/HowToContribute and 
http://wiki.apache.org/pig/HowToCommit to the pig wiki.  I lifted these 
straight from the hadoop site, with some editing to reflect the 
differences between the projects.  I'm not saying we have to follow 
hadoop's processes, but they seem like a good starting point for 
discussion.  So let the discussion begin.

I updated these pages to reflect the differences in the "patch 
available" mechanisms.  (Hadoop uses a Jira workflow state, while 
configured Pig to use a checkbox field on the issue.  Workflows are a 
pain to change in Jira, while fields are more lightweight.)

This does not imply that Pig must use the same patch procedures as 
Hadoop.  I initially configured Jira for Pig assuming it would use 
similar procedures, and these changes to the wiki are consistent with 
that.  But if folks wish to develop alternate procedures that's fine 
with me.
