Removed "insert" flag, inserting is by default for FileList.add().
Added "animate" flag to FileList.add().
Added logic to correctly detect when to insert/append elements whenever
the insertion point is visible or not.
Fixed "render next page" logic to work correctly when many pages of
files have been added.

The FileList.files model is now updated with file operations.
Adding files to the list will add to the model first, then to the DOM.
If the insertion point isn't visible yet, the file won't be added to the
DOM until the user scrolls down.

Updated unit tests to include checking for the correct insertion point.

- moved file selection code to FileList
- fix selection summary when all files are selected
- nextPage now auto-selects files if "select all" checkbox is checked
- fixed trashbin to use the same selection logic as FileList

- moved the summary code into a new class FileSummary
- FileSummary is calculated only once, then updated with add/remove
- added new OC.Util namespace for JS utility functions
