Massive refactor of sample manifest reception.

The issue originally started that all of the samples in a manifest were
then requested in parallel, which for a 3000 entry manifest caused pain.
This was an attempt to restructure the code in such a way to make that
far more friendly, but degenerated into fixing no end of bugs & issues.

Collect errors per tube.
Collect errors globally for missing tubes.
Global functions to deal with the various stages of processing.
Permit manifest upload even if there are errors, with a warning.
Hide controls in the face of success.
Display & check gender, hide order choice.
Detail with pages of tubes sequentially.

Process each tube on a page sequentially.
Process each page of tubes in parallel.
Wrote an _.regardless function that is $.when but right.
Refactored manifest template handling code

Move CGAP specific template info into separate file.
Dynamically load templates.
Build JsonTemplater.applicator instances once per template.
Drop the combinedData which can be retrieved from manifest structure.
Enable custom validations per manifest template.

Moved all of the template information into the manifest structure.
Fixed a bug: if the template didn't exist it would blow up!
Fixed a bug: if the column headers were incorrect it didn't fail!
Added custom validation callback to templates.
Handle non-CSV file uploads.

Fixed a bug: rejection of deferred wasn't manifest but model.
Ensure that manifest errors are not overwritten by messages.
If the file looks invalid UTF-8 at the start then assume Excel.
