Fixed a couple typos.
Changed to use fixed file names for input files.
Fixed bugs with packaging data and reading output logs.

Fixed
=====

* Fixed a bug that caused the output tarball to be packaged incorrectly.
  The full path to the simulation directory was included in the tarball
  rather that just the simulation directory itself.
* Fixed a bug that caused the stderr and stdout log file not to be
  read.

Added
=====

* Better error reporting to the server.
* Include a link to the uploaded data with the final update.
Changed run/upload to return a checksum and pickup URL.
Changed to show status message verbatim without escaping HTML.
