updated Rakefile with comments about how to use bundler/gem_tasks
bumped version
removed old custom rake gem tasks
now testing gestalt for ipod.  thanks to Alexander Khozya for the json
fixes bugs in wait_for_view_to_disappear and adds some more wait for view functions
lots of fixes and clarifications.  trying to replace wait_for_animation with wait functions
refactored scroll_until_i_see_row to optionally use a scrollToRowWithIdentifier table view category
deprecated scroll_until_i_see_row in favor of briar_scroll_to_row
which takes advantage of the new scroll to row marked server feature.

* removed funky herustic code in the row_visible? funtion because it
  is no longer necessary to do the last-row first-row offset checking
  because we can now scroll directly to a row
* refactored briar methods to use briar_scroll_to_row
continuing to replace calls to macro with functions
complete refactor of the date picker code to take advantage of
experimental server feature: :changeDatePickerDate
more tweaking
tweaking this and that
trying to handle navbar buttons better
