CodeShip-Bitbucket-Build_status.js

/*

A WebHook pipe who receive a Codeship notification when a build start or 
change and update the related status on Bitbucket.

This script need 3 script properties :
 + BITBUCKET_REPO The repository that will be updated
 + BITBUCKET_OWNER Username of `BITBUCKET_REPO` owner
 + BITBUCKET_PASSWORD /!\ Plain password of the owner. /!\
 
Codeship has more statuses than Bitbucket, a simple conversion is applied.
This can be changed in function 'convert' at line 102.
 + "testing" and "waiting" resolves to "INPROGRESS";
 + "success" resolves to "SUCCESSFUL";
 + "infrastructure_failure", "blocked", "stopped" and "error" gives "FAILED";
 + "ignored" is ignored (do nothing)
