Feature request: Provide more information than "Sending failed on: <some date and time>"

What steps will reproduce the problem?

1. Send any invalid survey.
2. Click <OK> on the "Upload Results" dialog to continue operation.

What is the expected output? What do you see instead?

I would like the user to see the human-friendly error message sent by Formhub 
when he looks on the "Send Finalized Form" screen. The user has no way of 
recalling _why_ the sending failed.  This makes support much more difficult, 
and makes transmission of more useful error messages pointless, since the user 
never sees them. 

I see "Sending failed..." with no other details.

What version of the product are you using? On what operating system?
ODK Collect 1.3.0(1030) -- android 2.3

Please provide any additional information below.

I am working on an extension to Formhub which will provide much more powerful 
form validation than is possible on the ODK unit.  For example, I will compare 
the GIS outline of the municipal area the surveyor claims to be in, with the 
GPS reading taken, and reject the form pending correction if he is not actually 
in that place. I will also check for incomplete entries in critical fields, 
etc. This should vastly improve the quality of collected data, compared to 
finding those inconsistencies during analysis weeks after the data are 
collected.

This extended validation will be accomplished along with loading ODK data into 
a GIS database in real time, rather than exporting from aggregate and then 
importing into the GIS system later.  When a field worker finds Acute Flaccid 
Paralysis we want a big red star to light up on the map in the Emergency 
Operation Centre as soon as she has connectivity.  A special vaccination team 
could start preparing to dispatch to that area rapidly.
