ODK Aggregate full changelog

installer now asks for an ODK Aggregate username for the super-user (not a Google e-mail account). Default password is aggregate.
banner displayed if super-user's password has not been changed from aggregate.
fix: column name generator bug (upload of form definition failed)
fix: add more detailed error messages when a submission is corrupted

changed behavior: simple JSON publisher now POSTs an application/json entity body; added option for how to treat binary content. Incompatible change; see Upgrading section if you were using the Z-ALPHA JSON Server
changed representation: ODK Tabled storage schema has been revised. Incompatible change; see Upgrading section if you used your server to upload or download data to ODK Tables. Syncing with ODK Tables is broken in this release. Only v1.3.4 on Google AppEngine works with the ODK Tables alpha (we are in the middle of changing table schemas).
fix: file exports were not properly writing UTF-8 character sets.
fix: postgreSQL failures on some forms (column names must be less than 63 characters)
Upgrade Aggregate’s Google publishers to use the updated Oauth2 libraries (e.g., Google Fusion Tables, Google Spreadsheet). Publishing from Google Apps domains does not work (it never has). This required a significant rewrite of the publishers so please notify the ODK core team of bugs!
