Cleanup of framework's use of @package and @subpackage labels and additional of labels for classes missing packages.
Moved all GridField related components to the one name.
Countless spelling fixes, grammar for other comments.
Link ClassName references in file headers.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
The classnames on the add-new button and breadcrumbs were not
translated due to the use of singular_name() instead of
i18n-singular_name() in GridFieldAddNewButton and GridFieldDetailForm.
* Alter Grid Field "Add New" Button to take the name of the table (i.e.
"Add Member")
* Alter table names in security section to be singular so the button
text makes sense
