Review request: Refactor SendToDocs

[GoogleCodeExporter]

Mercurial clone with changes to be reviewed:  simmonmt-refactor-sendtodocs

Revisions to be pulled from that clone (or "all"):

all

Purpose of code changes on the clone:

Refactoring SendToDocs; moving the methods which do the gdata magic into their 
own class so they're easier to test and so the higher-level code which calls 
them can be tested.

NOTES:
  - Sandor reviewed DocsHelper, DocsTagBuilder, tests for those, and the changes to GDataWrapper as part of 43134248c9 in simmonmt-refactor.  It may not be necessary to re-review them as part of this change.
  - This change could've been folded into simmonmt-refactor, but wasn't due to various problems I probably could've overcome.
  - I've intentionally left the logic in SendToDocs#uploadToDocs alone, and would rather not change it in this CL.  There's enough going on here as is -- I want this CL to be about moving the GData methods out of the way.

As Matthew commented, perhaps Sandor should be the one reviewing this, so 
assigning to him instead.
