This version of the Gantt chart supports nested charts. So Projects,
Versions, and Issues will be nested underneath their parents correctly.

Additional features:

* Move all Gantt code to Redmine::Helpers::Gantt class instead of having it in
  the Gantt class, controller, and view
* Recursive and nest sub-projects
* Recursive and nest versions
* Recursive and nest issues
* Draw a line showing when a Project is active and it's progress
* Draw a line showing when a Version is active and it's progress
* Show a version's % complete
* Change the color of Projects, Versions, and Issues if they are late or
  behind schedule
* Added Project#start_date and #due_date
* Added Project#completed_percent
* Use a mini-gravatar on the Gantt chart
* Added tests for the Gantt rendering

Fixed: parent project field doesn't include blank value when a member with 'add subproject' permission edits a child project (#4790).

Each version of a project can be shared with:
* subprojects
* projects in the project hierarchy: ancestors + descendants (needs versions management permission on the root project)
* projects in the project tree: root project + all its descendants (same as above)
* all projects (can be set by admin users only)

Notes:
* when sharing a version of a private project with others projects, its name will be visible within the other projects
* a project with versions used by non descendant projects can not be archived

Subprojects can be added to the projects for which the user has add_project permission.

  * Changed the Project has_many time_entry_activities to include all by default
    and provided an #active method to filter them to active ones only

* Added a reset button to delete all project specific activities.
* Added ProjectsController#reset_activities to remove the project
  specific activities
* Added a HTTP DELETE route for reset_activities
* Changed the permissions for managing project activities to have access to the
  ProjectsController#reset_activities action
* Added a way to bulk save Project specific Activities in ProjectsController
  * #save_activities will save all the changed activities, including update the
    existing records

* Ran the Rails upgrade
* Upgraded to Rails Engines 2.3.2
* Added a plugin to let Engines override application views.
* Converted tests to use the new classes:
** ActionController::TestCase for functional
** ActiveSupport::TestCase for units
* Converted ActiveRecord::Error message to a string.
* ActiveRecord grouping returns an ordered hash which doesn't have #sort!
* Updated the I18n storage_units format.
* Added some default initializers from a fresh rails app
* Changed the order of check_box_tags and hidden_field_tags.  The hidden tag
  needs to appear first in Rails 2.3, otherwise it will override any value in
  the check_box_tag.
* Removed the custom handler for when the cookie store is tampered with.
  Rails 2.3 removed the TamperedWithCookie exception and instead Rails will not
  load the data from it when it's been tampered with (e.g. no user login).
* Fixed mail layouts, 2.3 has problems with implicit multipart emails that
  use layouts.  Also removed some custom Redmine mailer code.
* Fixed a bug that occurred in tests where the "required" span tag would be
  added to the :field_status translation.  This resulted in an email string of:

    <li>Status<span class="required"> *</span><span class="required"> *</span>

  Instead of:

    <li>Status: New</li>
