Started basic comments / fixed Documentation

Started working on a basis for adding and displaying comments about a
task
Fixed up the documentation for the task history
Known bug still exists where, without updating the detail view before
editing again causes the task history to not update the list of members.
Comments is almost there. There is a few bugs when creating tasks and
putting a comment.
Fixed lingering text here as well?

Fully merged comments and history with star-of-refactored
Added history and comments class

Added history and comments view to the sidebar. This is a tabular,
hardcoded view. currently does not show up in task manager. The previous
version of saving history and comments does not work due to the merging
of the newish ui and refactor

Made it so that using the setter of an object in the task class will
check to see if it differs from its original value, then if so, add it
to the task's history list. fixed the up the comments from the breakage
due to the refactor.
TaskHistoryAndComments was renamed

This class was renamed to TaskActivitiesAndComments
