Changelist parsing fails when description contains reserved words

      The Hudson perforce plug-in is currently throwing exceptions for any changelists which contain "reserved" text in the changelist description. This appears to be introduced by the p4v client when creating changelist descriptions. Here is an example of a changelist which contains the problem (i.e. containing "Jobs fixed ..." in the changelist description):

      ===== begin output of "p4 describe -s 470718 =====
      Change 470718 by someuser@someclient on 2010/10/01 15:32:59

      Additional logic for org assoc validations at doc import time.

      Jobs fixed ...

      Jobs fixed ...

      ... //depotxyz/fileabc#6 edit
      ====== end output of "p4 describe -s 470718 ======

      In this case, the Hudson perforce plug-in fails and throws an exception:

      18:16:46 [5.5_Continuous_Build] $ /usr/local/bin/p4 describe -s 470718
      18:16:46 Caught exception communicating with perforce. Failed to retrieve changelist.com.tek42.perforce.PerforceException: Failed to retrieve changelist.

      The problem exists because the StringTokenizer used inside the ChangelistBuilder class also considers tabs as a delimiter when parsing the output of the "p4 describe" command. This means that the parser is incapable of using the indenting provided by the "p4 describe" output to distinguish between keywords generated by the Perforce server and keyword text that is part of the changelist description.

      Steps to reproduce:
      1) Create a changelist which contains "Jobs fixed ..." within the changelist description
      2) Create a Hudson job which syncs from Perforce (i.e. Poll SCM)

      When the job attempts to obtain changelist information for the changelist which contains "Jobs fixed ..." in the changelist description, it will throw an exception and will fail to advance to the next changelist. This effectively causes the job to continually fail at the same point, unable to obtain information about subsequent changelists.
