Rewrite XML Parsing for Query Recordsets

[StevenMMortimer]

This request changes the package to use one function called query_parser when parsing the results returned by Salesforce from SOQL queries. This was done to better handle foreign object and child-parent nested relationships that SOQL queries can return.

I believe this methodology or another methodology should be deployed soon in order to quickly resolve the backlog of issues described in #23

Link to query_parser code:

We're seeing the same issue -- would be great if this pull request could be integrated asap.

@ReportMort
After getting the same error as described in #23 (Error: All inputs to rbind.fill must be data.frames) , I now get a new error:

Error in t.default(unlist(x[setdiff(seq.int(length(x)), c(list_col, attr_col))])) : argument is not a matrix

Is there an easy fix for this?
If not, I can open an issue + put in more steps to reproduce

@nelsonauner The patch merged but it is not on the CRAN now. Please try the code from github or please wait just a few days, I will upload the current head version to CRAN.
