[misc] Upgrade to AngularJS 1.2.19
FILEMAN-28: Implement the file live table
FILEMAN-27: Implement a widget to display the tree of folders from a drive
* Simplify the way the paths are specified in the script service when executing batch operations (use folder/file notation).
* Add support for specifying the parent when creating a folder through the DriveSheet.
* Expose batch operations in the DriveSheet (for both files and folders).
* Extract some shared drive state (like the readOnly flag and the current folder) in an object that is placed in the global scope and is passed to the drive tree and live table directives.
* Create a 'files' directive that displays the files live table and the buttons to execute batch operations on selected files.
* Refactor the drive tree to use the drive object from the scope (the drive tree should update the selected folder on the drive object which will trigger an automatic update of the file live table thanks to Angular).
* Don't select the tree node when opening the context menu.
* Prevent multiple selection in the drive tree (for now).
* Use Bootstrap styles for file live table actions (button group).
* Update FolderSheet to use the simplified API for batch operations (regarding paths).
* Make the selection column optional in the live table.
