Adding support for the corporation name from the employment history

Adding support for the corporation name from the employment history of t...he CharacterInfo endpoint. This change is on Singularity now and will hit Tranquility on August 26th.

You may not want to actually pull this until the changes are on TQ, but I had a few minutes to spare now so figured I would toss this pull request together. :)

An example of this on Sisi can be found here: http://api.testeveonline.com/eve/CharacterInfo.xml.aspx?characterID=92168909
My guess is that this loop was written based off a model used elsewhere, where we were using the id to key a dictionary entry (e.g. `foo[id] = {'id': id, 'name': ...}`) and thus we needed the id extracted before the assignment line.

In this case, if you wanted to refactor it to get rid of the intermediate variables, that would be perfectly fine.
