Added SMTP configuration options
Bug #503 - removes inert navigation buttons

- the grey X navigation buttons indicating the first and last media
entries should not appear since they do not do anything
only remove the inert Xs when the user has one item
+ 'confirm' section for confirmation dialogues
+ implemented delete functionality
* fixed several instances of 'must be an instance of unicode, not str'
* Fix bad commit (oops!)
* Delete works now
Feature/Bug #519 - CloudFilesStorage.get_file() performance issue - Fix

*   `CloudFilesStorage.get_file()` now guesses the filepath without connecting to cloudfiles. Huge profits for xDSL-hosted or slow net machines.
Feature #489 - SMTP configuration options - Acts on feedback from cwebber.

Documentation Revision, clarification, and editing.

- a line in the .gitignore file to ignore the built documentation
  tree.

- a complete revision/editorial pass of all non-technical documents
  that outline process, project fundamentals, and background. These
  edits clarified the text, unified the style, and elaborated on
  stubs.
