Custom field names not decoded in SOAP ACCOUNTINFO

In the ACCOUNTINFO section of the results of the "get_computers_V1" and "get_snmp_V1" SOAP services, the names and values of custom fields are represented as opaque references such as "fields_3" or "1&&&2". This makes the fields' names and values meaningless to SOAP clients unless those clients have prior knowledge of the mappings of these names.

I've created a fix for this, which I've submitted to frankb for shepherding upstream. Creating this issue so that there's a more concrete record since I'm temporarily working on a different set of projects. The commit message from my bzrsend follows.

  Enhance handling of custom fields (i.e. other than TAG) in ACCOUNTINFO element
  of get_computers_V1 and get_snmp_V1 SOAP call results. Now
  ACCOUNTINFO/ENTRY.Name is resolved to the symbolic name of the field rather
  than e.g. 'fields_3'. Also, value of ACCOUNTINFO/ENTRY for custom field types
  CHECKBOX, RADIOBUTTON, and SELECT is now resolved to textual values. So where
  before we got:

  <ACCOUNTINFO>
   <ENTRY Name="fields_3">1</ENTRY>
   <ENTRY Name="fields_4>1&&&2</ENTRY>
  </ACCOUNTINFO>

  Now we get:

  <ACCOUNTINFO>
   <ENTRY NAME="FOO">Un</ENTRY>
   <ENTRY NAME="BAR">Deux</ENTRY>
   <ENTRY NAME="BAR">Trois</ENTRY>
  </ACCOUNTINFO>
